Hello, I'd like to start a discussion about how annotations are supported in maven builds. I'm currently trying to use some NetBeans Platform based annotations in maven projects and I'm encountering some problems.
1. http://jira.codehaus.org/browse/MCOMPILER-98 - -sourcepath needs to be always set to have the annotations processed. fixed in latest plexus compiler sources.. 2. some annotation processors require resources to be present on the sourcepath eg. one that generates java beans from schema or another one that checks for property bundle key presence. I'm not sure how to make this generally available to the processor. resources themselves (in src/main/resources) are not to be referenced I guess (as they could be on wrong <targetPath> or not filtered). So the only other option is to include the target/classes folder somehow with the correctly processed resources. Any other idea? 3. Some annotation processors generate xml files or META-INF/services content, some generate java files. the default output location for the processor is target/classes, which is fine for xml files, but it's inconvenient to generate java files there as they end up in the jar file then. I've tried to configure the compiler to use target/generated-sources/annotations as the output folder for sources (via -s <dir> switch). Unfortunately there are problems associated with that approach. a. the folder needs to exist up front or the compiler chokes on it. Doable with some ant-run scripting, but ugly. b. what to do with the resources there that need to be copied to the target/classes folder? Doable with resources:copy-resources but again ugly. 4. reporting from the annotations processors is broken - http://jira.codehaus.org/browse/MCOMPILER-66 Issue http://jira.codehaus.org/browse/MCOMPILER-75 seems to be dedicated to annotation support. Is anyone actively working on it? I'm volunteering to add some of the required switches as prameters for the compiler mojo, but I'm unsure how to proceed. Is it ok just to add the required stuff as mojo params, even if it will be unused by some of the other compilers? and even by the non 1.6 javac compilers? or have some new ways fo configuring the mojo (as pointed out in http://jira.codehaus.org/browse/MCOMPILER-14)? Thanks for any comments. Milos PS: I can provide a sample project with the above mentioned annotations being used if there is interest.
