Javac compiler plugin doesn't support -Werror
---------------------------------------------
Key: MCOMPILER-120
URL: http://jira.codehaus.org/browse/MCOMPILER-120
Project: Maven 2.x Compiler Plugin
Issue Type: Bug
Affects Versions: 2.1
Reporter: Christopher Webster
If I write a pom file like the following:
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.1</version>
<configuration>
<compilerId>javac</compilerId>
<source>1.6</source>
<target>1.6</target>
<compilerArguments>
<Werror />
<Xlint:all />
</compilerArguments>
<showDeprecation>true</showDeprecation>
</configuration>
</plugin>
and if there are only warnings, then the build will not fail as intended by the
compiler Argument. The reason is that in compileInProcess the exit code from
javac is only considered if there are no messages. In the case of treating
warnings as errors, there will be messages but no errors so the intention of
the build failure is lost.
