Description

When you compile a java project with -X maven option and <fork>true</fork> in the maven-compiler-plugin configuration, the following extra files are written to target\classes and bundled in the root directory of the jar:

javac.bat
org.codehaus.plexus.compiler.javac.JavacCompiler8515975925044691799arguments

The precise name of the arguments file varies from build to build. The exact configuration we are using is:

 <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.1</version>
                    <configuration>
                        <source>1.6</source>
                        <target>1.6</target>
                        <fork>true</fork>
                        <showDeprecation>true</showDeprecation>
                        <showWarnings>true</showWarnings>
                    </configuration>
 </plugin>

We originally saw this in version 2.3.2 of the maven-compiler-plugin. I've verified that it also occurs in version 3.1. We are able to work around this issue by setting fork to false. The issue also does not occur if -X is not used. This can be reproduced in any maven java project.
