I use org.eclipse.jdt.core as a dependency in my code. I want to perform a small modification (make the constructor public) to the abstract class ASTNode in org.eclipse.jdt.core. After performing the modification I want to build it and use the compiled jar file in my project as a dependency jar.
Hence I want to build Eclipse JDT Core from source code via Git. Naïvely, I cloned
git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git and executed mvn -P build-individual-bundles package as suggested in POST.
I get the error below after a few minutes. Any ideas? TIA!
