Filip Bellander created MCOMPILER-248:
-----------------------------------------
Summary: Missing compiler in configuration creates cryptic error
Key: MCOMPILER-248
URL: https://issues.apache.org/jira/browse/MCOMPILER-248
Project: Maven Compiler Plugin
Issue Type: Improvement
Affects Versions: 3.1
Environment: CentOS server running jenkins.
Reporter: Filip Bellander
In our configuration file, we had an old path to javac specified (we updated
our java recently, and thus the given path was incorrect). Instead of giving
some information that the compiler that maven was trying to use to compile our
sources was missing, this was given:

So, instead of this error, I suggest that if the compiler (javac) can't be
found, inform the user of this instead of giving this strange error. Took us
half a day to figure out what could have gone wrong, and the error message
didn't really help.
