compileSourcesArtifact ceased to work

[Gražvydas Valeika]

Hello,

it seems Mojo's Maven Plugin for GWT is alive and well. 

I just found that it has 2.8.0-SNAPSHOT version!

But I was hit by not working compileSourcesArtifact.

There is stackoverflow question about it: http://stackoverflow.com/questions/37295512/compilesourcesartifact-not-working

Unfortunatelly solution offered by Thomas Broyer is not very helpfull if you have reason not to package java files into module jar at first place.

Could somebody comment what happened to compileSourcesArtifact? Is there any hope for its revival?

Best regards,

Grazvydas

See https://github.com/gwt-maven-plugin/gwt-maven-plugin/issues/127 for an alternative (the proper way if you ask me, compileSourcesArtifact is a crutch for when your build is not properly organized/modularized).

Also have a look at the comments on the stackoverflow question.

As for why it doesn't work, no idea sorry; but updating your build to not using it will only do good, so I'd suggest trying that instead of even trying to debug the issue (if you ask me, that "feature" should simply be removed; but I'm neither a maintainer nor even a user, so…)

it seems that my problem was not related to sources jar availability.

Building monolitic jars doesn't help.

I was suspecting that 2.8-SNAPSHOT compiler fails because it misses sources, but now I'm not sure.

But this issue is out  of scope of this list,

That'd mean either a corrupted class file, a class compiled for Java 9 (using OpenJDK 9 already?), or GWT looking at a file that's not actually a class file:

http://grepcode.com/file/repo1.maven.org/maven2/org.ow2.asm/asm/5.0.3/org/objectweb/asm/ClassReader.java#169

No Java 9. 

Corrupted class file - can't see how - I'm rebuilding everything with mvn clean compile package. It can be custom gwt library taken from maven repository and bult with java 7. But, please correct me - how gwt compiler is related to compiled classes - I expect that it compiles sources to classes by itself and then processes its own produced bytecode.

Did you managed to fix that? I'm stuck with this issue.
