Rishabh Chandra commented on MCOMPILER-71:
------------------------------------------

I have faced this issue myself. I tried both 2.0 and 2.0.1 and they did not work.
Then i used the excludes and got the code to compile. As the package-info file is only for javadoc I just ignored it. This is the only solution i could get to work.
<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<fork>true</fork>
					<meminitial>128m</meminitial>
					<maxmem>512m</maxmem>
					<source>1.5</source>
					<target>1.5</target>
					<excludes>
						<exclude>**/package-info.java</exclude>
					</excludes>				
				</configuration>
			</plugin>

>             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

> 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.
