Hey there,
this is my post, please let me know if i am not using the forum correctly.

I want to package the standalone eclipse compiler.
The following steps did work before, but don't work anymore on the current version.

git clone https://git.eclipse.org/c/jdt/eclipse.jdt.core.git/
cd org.eclipse.jdt.core
mvn package

If i try it on the current version, i get

[FATAL] Non-resolvable parent POM for eclipse.jdt.core:eclipse.jdt.core:4.11.0-SNAPSHOT: Could not find artifact org.eclipse:eclipse-platform-parent:pom:4.11.0-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ eclipse.jdt.core:eclipse.jdt.core:4.11.0-SNAPSHOT, /home/jan/Repositories/eclipse.jdt.core/pom.xml, line 15, column 11
 @

Is this the right way to build the stand-alone compiler? If so, how can i resolve the artifact error? Are there any resources on the build process? Also, which one of the branches in the repository would be a wise choice?

Thank you very much for reading this post.

I believe it's trying to point at this:

https://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/tree/eclipse-platform-parent/pom.xml

You can build using the following code

git clone https://git.eclipse.org/c/jdt/eclipse.jdt.core.git/
cd eclipse.jdt.core/org.eclipse.jdt.core
mvn clean verify -DskipTests=true -Pbuild-individual-bundles

The ecj will be available as eclipse.jdt.core/org.eclipse.jdt.core/target/org.eclipse.jdt.core-*-SNAPSHOT-batch-compiler.jar

Thank you very much for the replies! The command works as desired. :)

Is this documented somewhere? I would like to have a reference for future updates and breaking changes in the build process.

You will need to go to Project->Clean...,then build your project. This will work, even when your source code does not contain any main method to run as an executable program. The . class files will appear in the bin folder of your project, in your workspace.

Hello Ed Merks, I have the same problem as you answered in the question 13 years ago, I think it was right. But now this link is not working. Can you suggest another one or how to compile it all, if I have the same error at the moment? I really appreciate any help you can provide.
