[scr] java.lang.IncompatibleClassChangeError: Implementing class
Hi,
while compiling a rather simple project with a one method interface, i get the scr package phasis failing [0] , apparently when processing the only reference i use in my project [1]. I’m out of ideas and hope this rings a bell to someone, or can someone guide me through the way to debug the scr generator project? i’ve tried mvnDebug + remote debugging on port 8000, but i don’t manage to have my ide (intellij) even loading the class.

However, i’ve moved some suspected class out of the interface, only in the implementation, and get the same error, but happening a bit further, basically in the component implementing the interface [0]. I guess i’m next to it :-) but still can’t find that. I’m using clapper for class information browsing through 2 dependencies [1], the incriminated class is org.clapper.util.classutil.ClassInfo. Those dependencies required me to add the maven.clapper.org repository within the project.

[solved][scr] java.lang.IncompatibleClassChangeError: Implementing
class
Posted by Nicolas Peltier <np...@adobe.com>.
Thanks Robert, that didn’t work out. I “fixed" it by removing all the javautil references from internal private methods signatures…this probably isn’t right, but don’t have much more time to spend on this, and wouldn’t know exactly how to file a bug

I removed the dependency and got the same error, so i guess problem is a javautil class uses an API incompatible with asm-all used in scr. Is there a way to ask scr validator not to check too far? :-)

Re: [scr] java.lang.IncompatibleClassChangeError: Implementing class
Posted by Nicolas Peltier <np...@adobe.com>.
Right thanks a bunch.. i need asm at runtime (i embed it) but not at compilation time (and definitely not at description gen time). I removed the dependency and got the same error, so i guess problem is a javautil class uses an API incompatible with asm-all used in scr. Is there a way to ask scr validator not to check too far? :-)

Re: [scr] java.lang.IncompatibleClassChangeError: Implementing class
Posted by Robert Munteanu <ro...@apache.org>.
Maybe there's a clash between the ASM version used by the SCR plugin
(4.0) and the one used by your project ( 3.3.1 ) ?

However, i’ve moved some suspected class out of the interface, only in the implementation, and get the same error, but happening a bit further, basically in the component implementing the interface [0]. I guess i’m next to it :-) but still can’t find that. I’m using clapper for class information browsing through 2 dependencies [1], the incriminated class is org.clapper.util.classutil.ClassInfo. Those dependencies required me to add the maven.clapper.org repository within the project.

Re: [scr] java.lang.IncompatibleClassChangeError: Implementing class
Posted by Nicolas Peltier <np...@adobe.com>.
Thanks Robert,
i don’t manage to run the build with the proposed option. However, i’ve moved some suspected class out of the interface, only in the implementation, and get the same error, but happening a bit further, basically in the component implementing the interface [0]. I guess i’m next to it :-) but still can’t find that. I’m using clapper for class information browsing through 2 dependencies [1], the incriminated class is org.clapper.util.classutil.ClassInfo. Those dependencies required me to add the maven.clapper.org repository within the project.

Can you try loading your build with -verbose:class and see if anything
stands out? I'd be looking for classes loaded from unexpected
locations or old versions of classes.
