Is it possible to get maven to accept maxerrs for its compiler plugin?

I have a project where I am responsible for fixing some errors and another developer is responsible for other errors. The number of errors is well over a hundred, and as I'm fixing my errors, her errors are piling up. I'm at the point where I see 99 of her errors and one of mine, and I assume I will soon get to a point where it is 100 of hers. I looked into using this configuration for maven:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <compilerArgument>-Xmaxerrs 1000</compilerArgument>
  </configuration>
</plugin>

But no dice:

Failure executing javac,  but could not parse the error:
javac: invalid flag: -Xmaxerrs 1000
Usage: javac <options> <source files>
use -help for a list of possible options

On the command line using javac, the maxerrs flag works as expected, but I can't seem to make the leap to maven with it.

Any ideas?

Solution

  • Using the "Map syntax" worked for me:

      <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
      <fork>true</fork>
      <compilerArguments>
        <Xmaxerrs>1000</Xmaxerrs>
      </compilerArguments>
    </configuration>
  </plugin>

    The option is passed as expected:

    $ mvn clean compile -X

    The odd part is that I get the exact same debug output (with the exact same Command line options) when using the alternative configuration you provided... except that it fails due to a Failure executing javac. You should raise a Jira issue, there is definitely something weird.
