javac compilation error for package-info.java containing package annotation
---------------------------------------------------------------------------
Key: MCOMPILER-71
URL: http://jira.codehaus.org/browse/MCOMPILER-71
Project: Maven 2.x Compiler Plugin
Issue Type: Bug
Affects Versions: 2.0.2
Environment: Windows XP SP2
JDK 1.5.0_15
Reporter: Gabriel Forro
Attachments: compile_error_2.0.2.log
The package-info.java files can not be compiled in Maven 2 if the 2.0.2
maven-compiler-plugin is used. package-info.java files can be compiled by
earlier versions of the maven-compiler-plugin (I have tried 2.0 and 2.0.1).
Newer snapshot versions does not work also and it fails in the same error (I
have tried version 2.1-snapshot).
This problem can be caused by an unusual behavior of the javac from jdk 1.5.
This behavior is as follows:
You can not use '/' file separator during compiling package-info.java (for
instance "javac sk/forro/package-info.java"). You must use '\' separator (for
instance "javac sk\forro\package-info.java"). If you use the '/' separator you
get the the compilation error reported by this bug (package annotations should
be in file package-info.java). This is javac 'feature' has been removed in jdk
6 and in jdk 6 you can use either '/' or '\' - it does not matter.
It looks like the maven-compiler-plugin or one of its components (I mean
plexus-x artefacts used by maven-compiler-plugin) uses '/' instead of the '\'
in the MS Windows environment.
I have attached a log file of an unsuccessful build (generated by mvn install
-X)
A possible workaround to solve this problem temporarily:
The compilation successes if I use either an older version of
maven-compiler-plugin or jdk 6 or do not use package-info.java files at all.
