PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build

[Thomas Broyer]

Hi all,

If you're using 2.7.0-SNAPSHOT, your build might start failing as of today as we started unbundling dependencies from gwt-dev as published to the Central Repository.

java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

If you get this error, be sure to also update your gwt-maven-plugin to the latest 2.7.0-SNAPSHOT too.

If that doesn't work, add gwt-dev or (better) gwt-codeserver as a project dependency (and report the problem to https://groups.google.com/d/forum/codehaus-mojo-gwt-maven-plugin-users). This is likely to become the preferred way to use GWT in the future, and the gwt-maven-plugin might stop automatically adding GWT deps to the classpath in gwt:compile or gwt:run in a future version (probably not 2.7 though): as we'll unbundle more dependencies from gwt-dev (and gwt-user), you might want to gain control over those dependencies (e.g. using a newer version of Guava, or ASM, etc.) and this is not possible with plugin dependencies as it's done today within the gwt-maven-plugin.

Also noteworthy: that same change also turned com.google.gwt:gwt into a BOM (bill of material); that means that instead of including the <version> in all your GWT dependencies you can now declare com.google.gwt:gwt into your dependencyManagement section with <scope>import</scope>. As a bonus, it should ensure transitive dependencies to GWT will all use the same version, so you'll have fewer risks of conflicts.

I'll soon update the GWT samples, WebAppCreator templates and various archetypes to use those new "best practices".

Great news! thanks to all the team for all the work on SDM, did the migration to 2.7 last week, brought me the smile again while working with GWT.

Yes, there's actually a bug in the parent POM: https://gwt-review.googlesource.com/9642

(note: you need more than asm –see POM–, but possibly only under some conditions – classic DevMode?)

I think I'm getting two errors relating to the bugs in the POM that Thomas mentions above:

[ERROR] Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.7.0-SNAPSHOT:compile (default-cli) on project UsavAppV7: Failed to resolve artifact: Some problems were encountered while processing the POMs:

I have tried adding gwt-dev, gwt-codeserver, and the asm dependency but still getting it. Also tried forcing an update of snapshots/releases but no change.

I'm still a bit green when it comes to maven.

Which version of Maven are you using? Also, have you configured the google-snapshots both as a repository and pluginRepository? (I think this is needed for the plugin to resolve its dependencies)

I was fighting yesterday with a discrepancy between Maven 3.0.5 and 3.1 / 3.2 with the maven-invoker-plugin (used to run tests of the gwt-maven-plugin): things passed with 3.1 (on BuildHive) and 3.2 (on Travis-CI) but failed on my machine (3.0.5). Trying with 3.2.3 on my machine, things worked. The error was exactly the same wrt com.google.web.bindery:requestfactory.

The error about ASM is strange though, it's in Central so it should Just Work™, unless you have some repository/mirror configuration getting in the way?

When I checked the https://gwt.googlesource.com/gwt/+/master/samples/dynatablerf/pom.xml sample it had also the  <url>https://oss.sonatype.org/content/repositories/google-snapshots/</url> as a pluginRepository ?

Where do you deploy the latest gwt-maven snapshot to sonatype or codehaus ?

[Thomas Broyer]

gwt-maven-plugin snapshots are deployed to codehaus, but the plugin depends on GWT snapshots which are at sonatype, and Maven thus uses the pluginRepositories to download them as dependencies of the gwt-maven-plugin (it doesn't look like it uses the repositories listed in gwt-maven-plugin's own POM).

Does it change anything if you declare google-snapshots as a pluginRepository as well?

[Ümit Seren]

no it didn't help unfortunately. 

But I upgraded to maven 3.2.1 and the error went away. 

[Thomas Broyer]

This is strange, because I tested the samples with Maven 3.0.5 (this is still my default version) and didn't have this problem :-/

[Ümit Seren]

Hmm that's weird. I remember that when I tried to compile the same app with 2.7.0-SNAPSHOT (gwt-maven plugin) two weeks ago it worked fine with maven 3.0.5.

However I have now a different issue: 

I have used your gwt archetype (https://github.com/tbroyer/gwt-maven-archetypes)  and I have three modules (app-client, app-server and app-shared) inside a parent pom project (app) . 

When I run "mvn clean install" in app-client everything works fine (gwt compiles, finishes). 

However when I run "mvn clean install" in parent "app" pom projet I get following error:

Somehow I made the requestfactory error go away but I'm still getting this one:

I'm using Eclipse Luna with maven 3.2.1. Very odd.

Ok this error has nothing to do with GWT but with Errai. They iterate through the current working directory (CWD) to find the output folder to generate the server side marshalling classes. If the CWD has symbolic links this will apparently result in a NullPointerException. I have the strong feeling this is a bug (it should have a nullpointercheck). 

[tskardal]

I'm' also having some trouble. I get errors related to both requestfactory and asm-parent.
You can see the error message and pom.xml at this gist: https://gist.github.com/tskardal/0d8287da4265c0fddfc8

I've created a project using the maven archetype, modified the versions and added the snapshot repos.

[Brandon Donnelson]

Thomas I'm noticing the issue coming up on my config. I haven't drilled down to why yet. I copied the samples config.

I found the reason, trying to find a workaround.

The repository definition is causing it to try to download from snapshots where it doesn't exist. 

[Colin Alworth]

Looks like codehaus's snapshot repo is down, so I'm unable to get the latest gwt-maven-plugin. This url gives a 504 gateway timeout from ngnix for me:
https://nexus.codehaus.org/content/groups/snapshots-group/org/codehaus/mojo/gwt-maven-plugin/2.7.0-SNAPSHOT/maven-metadata.xml

If I set gwt-user and gwt-servlet to 2.7.0-SNAPSHOT and gwt-maven-plugin to 2.6.1, I get the NoClassDefFoundError:

All GWT copies on the classpath are 2.7.0-SNAPSHOT, its just building under gwt-m-p 2.6.1.

Is this really expected? I'm probably misunderstanding how scope=import works and its importance (ha) to the build, but the strong implication seems to be that gwt-m-p is pulling in gwt-dev, but not transitive dependencies.

Pre-send edit: codehaus is back, pulling down results now. As with others, I am getting that org.ow2.asm:asm-parent:pom:5.0.3 is inexplicably missing, even if I delete it from my .m2/repository and the build *downloads* it, it claims it can't find it.

Is there any chance that this is a 'feature' of scope=import, that you have to pull content from the same repos that the import'd pom came from, and that you can't get it from even the other defaults?

For reference sake, the project I'm building is https://github.com/niloc132/gwt-rpq on the 2.7.0 branch - first build rpq itself (gwt vers doesnt matter), then build gwt-rpq. Maven version included in the gist above.

[Brandon Donnelson]

It appears that the  org.ow2.asm:asm-parent:pom:5.0.3 @ is fixed after upgrading to maven 3.2.3. The pom issue goes away.

Hi Thomas,

Thanks, I'm up and running again with dependency on gwt-dev and gwt-codeserver...

Just checking: Presumably this is being pragmatic, working with what Maven gives us, as they are really plugin dependencies? ie the code I'm compiling shouldn't be coupled to any of gwt-dev or gwt-codeserver?

Thanks again, lots of beers waiting for you if I ever get the chance.

Sam

[Drew Spencer]

Hmm, I don't think I can update the maven version in Eclipse properly - on 'Installations' page it says "Embedded runtime is always used for dependency resolution".

Can we switch to gradle? :D

[Ümit Seren]

Haven't used eclipse for a long time but I guess you can tell it to use the installed maven version instead of the embedded runtime. 

Sometimes I have the feeling that one needs a Phd degree to master maven and probably two if you include the integration into an IDE ;-)

All GWT copies on the classpath are 2.7.0-SNAPSHOT, its just building under gwt-m-p 2.6.1.

Is this really expected?

Yes.

g-m-p 2.6.1 assumed that gwt-dev had no dependency, so it just put gwt-dev in the classpath for the forked JVM without trying to resolve transitive dependencies. I fixed that recently in g-m-p 2.7.0-SNAPSHOT (https://github.com/gwt-maven-plugin/gwt-maven-plugin/commit/33e0b541f02c7cadff7f13c921d8e8f8a0a8ec79 and https://github.com/gwt-maven-plugin/gwt-maven-plugin/commit/2b60f6306fdce410399dd4c76c07ea91884abb3b)

If you add gwt-dev as a dependency of your project, then the transitive dependencies will be added from the project (and the g-m-p will add  gwt-dev a second time, from its own dependencies).

 

I'm probably misunderstanding how scope=import works and its importance (ha) to the build, but the strong implication seems to be that gwt-m-p is pulling in gwt-dev, but not transitive dependencies.

It's unrelated to scope=import, only to the fact that gwt-dev didn't have any transitive dependency until recently, and the g-m-p was coded with that assumption.

 

Pre-send edit: codehaus is back, pulling down results now. As with others, I am getting that org.ow2.asm:asm-parent:pom:5.0.3 is inexplicably missing, even if I delete it from my .m2/repository and the build *downloads* it, it claims it can't find it. Full gist from debug log: https://gist.github.com/niloc132/da63de6d8e8da90f49d7

This is really really strange, as I'd swear that everything was working for me with Maven 3.0.5 (before sending the patch to update the samples in GWT, I ran "mvn clean verify" and then "mvn gwt:run"). I never "mvn install" (or exceptionally once or twice a year) anything on my machine so the snapshots were all coming from the remote repositories.

As far as I can tell, you can tell it to execute with another runtime, but it always uses the embedded one for dependency resolution.

I agree. It's one of those "it's not rocket science, that would be easy compared to this" things :O

FWIW my app seems to compile and run ok using gwt-maven-plugin 2.6.1 with gwt 2.7.0-SNAPSHOT... gwt:run launched the codeserver and the auto recompile seems to be working :)

[Brandon Donnelson]

Hi Drew, what version of maven are you using? mvn -version?

[Drew Spencer]

Hi Brandon. I've never used maven from the command line but my eclipse (fresh luna) tells me my embedded version is 3.2.1 but I installed 3.2.3 and am using that, though as I mentioned above eclipse always uses the embedded version for dependency resolution.

So I'm launching with 3.2.3 and dependencies are done with 3.2.1 as far as I can tell.

[Brandon Donnelson]

Oh interesting I haven't considered the Eclipse issue yet. Good to know.

I'll be looking at the GPE configuration system later today and this weekend, I noticed it was broken with the BOM config, so suspect I could see the issue in that config and I'll check out the options. I'll do some more debugging in Eclipse and see what happens with that.

Thanks for the info,

Brandon

Have a good day,
Brandon Donnelson

OK, problem reproduced/acknowledged. I know what in the plugin causes the error, but it's code a copy/pasted from another module without really understanding it (and using an API with absolutely zero documentation) so it might not be that easy to fix.

I think we'll really require everyone to explicitly declare gwt-codeserver as a project dependency.

Let's see how it goes in 2.7 beta1, without snapshots in the equation.

[Brandon Donnelson]

Just a note, I'm digging into the GPE m2e project configurator. It looks like I've got to add a way to ready the dependency management (BOM). I'll have a test case setup shortly so I can start getting it to read the pom.xml configuration. Do you think anything is going to change upstream yet? From the way it looks so far its a maven bug and not an issue in the gwt configuration. 

[Brandon Donnelson]

Update, GPE seems to be working, so I'm going to run more tests to verify. 

[Thomas Broyer]

I think (hope!) I fixed it: https://github.com/gwt-maven-plugin/gwt-maven-plugin/commit/5d1c15f0fca3cfce5618c5c96cfa12c88534fc31 

[Brandon Donnelson]

Nice job

[Drew Spencer]

I'm using the snapshot since yesterday and it seems to be working great.
