JavacCompiler treat localized warning messages as errors
--------------------------------------------------------
Key: MCOMPILER-109
URL: http://jira.codehaus.org/browse/MCOMPILER-109
Project: Maven 2.x Compiler Plugin
Issue Type: Bug
Reporter: Kohsuke Kawaguchi
This is really a bug in plexus-compiler-javac, not that of a Maven plugin.
Javac uses localized messages for "error" and "warning" for languages like
Japanese, but JavacCompiler.parseModernStream(...) and parseModernError(...) is
hard-coded to only understand English words "warning" and "error".
In particular, in line 535, the code treats any keyword but "warning" as
errors, so the Japanese word "警告" (meaning warning) is
interpreted as an error.
{code}
isError = !msg.startsWith( WARNING_PREFIX );
{code}
As a fix, I suggest you check the exit code from javac to determine if there
were any errors --- if it returns 0, treat everything as warnings.
