[jibx-users] JiBX vs Lombok clash in Eclipse w/Maven

[Francis L. <fra...@ex...>]

I have  a problem with a project that uses both JiBX and Lombok (http://projectlombok.org/) Eclipse extension. The problem shows up when building within Eclipse (using the Maven m2e jibx plugin).

Running Maven at the command line works fine - code gets generated, compiled and packaged.

Lombok supplements the java compiler to generate methods from annotations at compile-time. It is very nice - one of these things you can't live without once you start using them. 

I will file a bug report but I am posting this first here so that it can be discussed.

I had to revert to JiBX 1.2.2 to get this stack trace as v1.2.3 was eschewing most of it :

Execution gencode of goal org.jibx:maven-jibx-plugin:1.2.2:schema-codegen failed: An API incompatibility was encountered while executing org.jibx:maven-jibx-plugin:1.2.2:schema-codegen: java.lang.LinkageError: loader constraint violation: when resolving method "lombok.eclipse.TransformEclipseAST.transform_swapped(Lorg/eclipse/jdt/internal/compiler/ast/CompilationUnitDeclaration;Lorg/eclipse/jdt/internal/compiler/parser/Parser;)V" the class loader (instance of org/codehaus/plexus/classworlds/realm/ClassRealm) of the current class, org/eclipse/jdt/internal/compiler/parser/Parser, and the class loader (instance of <bootloader>) for resolved class, lombok/eclipse/TransformEclipseAST, have different Class objects for the type ransformEclipseAST.transform_swapped(Lorg/eclipse/jdt/internal/compiler/ast/CompilationUnitDeclaration;Lorg/eclipse/jdt/internal/compiler/parser/Parser;)V used in the signature
