Hi,

I just tried to rebuild my project with gwt 2.8.0-rc1 using gwt-maven-plugin net.ltgt.gwt.maven 1.0-rc-6.

Strange thing happened with project source roots.

Compiler can see only my project's src/main/resources directory and ignores src/main/java.

After I moved src/main/java content to src/main/resources - project builds successfully.

Earlier I could successfully build project using same maven configuration and gwt 2.8-SNAPSHOT.

Any ideas?

This is really strange. Can you run Maven with -X and check the classpath and arguments passed to GWT? (you may want to also pass -Dgwt.logLevel=INFO)

Hi,

I have run with your parameters, but can't see any mentions nor about gwt-dev.jar nor com.google.gwt.dev.Compiler. Could you point more directly how to check what arguments are passed to GWT?

compileSourceRoots and extensive sourcepath are defined in maven-compiler-plugin sections, but, I suspect, they are not related to my problem.

Sections, related to gwt-maven-plugin, as I see them. Full output, I guess, would be too noisy for list:

Oh sh** they're only displayed for gwt:codeserver and gwt:devmode, not with gwt:compile!

Would you mind testing with 1.0-SNAPSHOT?

With 1.0-rc-6, only option would be debugging the plugin (using mvnDebug instead of mvn, and plugging a Java debugger)

src/main/resources (and other resources) is copied (and possibly "filtered") by the maven-resources-plugin, and src/main/java (and other source roots) is copied by gwt:import-sources, so all sources are in (in your case) target/Metrika/WEB-INF/classes.

So I'd suggest you check in target/Metrika/WEB-INF/classes that everything's there.

Honestly, I don't really understand how things could work with GWT 2.7.0 but fail with GWT 2.8.0-rc1, without changing the gwt-maven-plugin, but work if you move things from src/main/java to src/main/resources.

All I can do is give hints at how to debug the situation.

(btw, this is all assuming you "mvn clean" between each change; because… well, Maven)

mvn clean - sure

Regarding vesions. I didn't try GWT 2.7.0. I was experimenting with 2.8.0-SNAPSHOT, because of this I switched to net.ltgt.gwt.maven plugin. Now I'm confused, but feel positive that 2 weeks ago project was building (with 2.8.0-SNAPSHOT). Now tried 2.8.0-rc1 - problem, also tried GWT 2.7.0 - the same problem as 2.8.0-rc1, so this is not regression, but it is very strange that with 2.8 snapshot I could build project.

According lines of your comment about maven-resources-plugin, I see its debug log:

It seems that maven-resources-plugin sees couple of files in src/main/resources directory and copies them to target/Metrika/WEB-INF/classes. But thats all. It doesn't copies anything from src/main/java. And target/Metrika/WEB-INF/classes contains lot of *.class files coming from maven-compiler-plugin, but no *.java files. I don't see maven-resources-plugin mentioned in my pom files, so it runs with configuration obtained from other plugins. And it seems that it cares to copy src/main/resources only.

This is by design (sorry, I hadn't worked on the project for months and forgot a bit how it worked in details).
src/main/resources (and other resources) is copied (and possibly "filtered") by the maven-resources-plugin, and src/main/java (and other source roots) is copied by gwt:import-sources, so all sources are in (in your case) target/Metrika/WEB-INF/classes.
So I'd suggest you check in target/Metrika/WEB-INF/classes that everything's there.

Honestly, I don't really understand how things could work with GWT 2.7.0 but fail with GWT 2.8.0-rc1, without changing the gwt-maven-plugin, but work if you move things from src/main/java to src/main/resources.

All I can do is give hints at how to debug the situation.
(btw, this is all assuming you "mvn clean" between each change; because… well, Maven)

mvn clean - sure

Regarding vesions. I didn't try GWT 2.7.0. I was experimenting with 2.8.0-SNAPSHOT, because of this I switched to net.ltgt.gwt.maven plugin. Now I'm confused, but feel positive that 2 weeks ago project was building (with 2.8.0-SNAPSHOT). Now tried 2.8.0-rc1 - problem, also tried GWT 2.7.0 - the same problem as 2.8.0-rc1, so this is not regression, but it is very strange that with 2.8 snapshot I could build project.

I can't believe it'd work with snapshot and fail with RC1, given they're currently exactly the same.

It seems that maven-resources-plugin sees couple of files in src/main/resources directory and copies them to target/Metrika/WEB-INF/classes. But thats all. It doesn't copies anything from src/main/java.

Unless you explicitly declare src/main/java as a resource dir, that's the expected behavior.

And target/Metrika/WEB-INF/classes contains lot of *.class files coming from maven-compiler-plugin, but no *.java files.

That means you should copy them yourself; easiest is to use gwt:import-sources (see samples in the GWT SDK, or in the GWT repository)

That said, I highly recommend splitting client and server code into separate Maven modules, then you can simply use <packaging>gwt-app</packaging> for the client code and only have to configure the module name and short name.

See https://tbroyer.github.io/gwt-maven-plugin/ (intro, usage and migration should help understand the design)

I don't see maven-resources-plugin mentioned in my pom files, so it runs with configuration obtained from other plugins. And it seems that it cares to copy src/main/resources only.

maven-resources-plugin's resources goal is bound to the process-resources phase by default in the jar and war lifecycles; see https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

That solved problem:

<build>

</resource>

<directory>src/main/resources</directory>

</resource>

</resources>

I settled at maven-war-plugin way of doing things. <packaging>gwt-app</packaging> worked, but I couldn't find a way to exclude some junk.
