Olivier Lamy commented on MCOMPILER-307:
----------------------------------------
currently I got such error message which looks to be a human readable error
message :) `Cannot run program "/invalid/path/to/bin/javac"`

> Improve error message when compiler executable path invalid
> -----------------------------------------------------------
>
> Key: MCOMPILER-307
> URL: https://issues.apache.org/jira/browse/MCOMPILER-307
> Project: Maven Compiler Plugin
> Issue Type: Improvement
> Affects Versions: 3.6.2
> Reporter: Bryan Parry
> Priority: Major
> Attachments: Maven compiler error.txt
>
>
> When the compiler executable path and fork properties are set, and also the
> compiler executable file does not exist, a CompilationFailureException is
> thrown with a message: "Compilation failure". The plugin should be able to
> check whether the compiler executable is a valid file, and print a message if
> it does not exist (e.g. {{"Path to compiler executable " + path + " is
> invalid. File not found."}})
> Here is an example of the maven compiler properties that can cause the error
> to occur:
> {code}
> <properties>
>
> <maven.compiler.executable>/invalid/path/to/bin/javac</maven.compiler.executable>
> <maven.compiler.fork>true</maven.compiler.fork>
> </properties>
> {code}
> This error can be tricky to debug when a specific maven profile is enabled
> only on a build server by default.
