[SOLVED] Scala maven plugin doesn't compile with StackOverflowError

Scala maven plugin doesn't compile with StackOverflowError

I found a bug related to Scala-maven-plugin in my Maven project. I have a very long Sequence of features (for Machine Learning purposes) I hand-coded (74 elements).

I added one element in the sequence and it doesn't compile anymore. If I comment any element of this sequence, the number of elements decreases and it compiles.

For more information, here is the final output of my compilation:

[ERROR] Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.3.1:compile (default) on project SecretProject: wrap: org.apache.commons.exec.ExecuteException: Process exited with an error: 240 (Exit value: 240) -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR] For more information about the errors and possible solutions, please read the following articles:

Plus the very beginning of the StackTrace:

(modified project name)

Did anyone encounter a similar issue with Scala-maven-plugin?
Does Scala-maven-plugin parser (in the compiler) have any sort of hard limit for Sequences parsing?
How to solve it and compile my project?
Why does it work with IntelliJ compilation ("play" button) but not with Maven compilation?

EDIT:

I'm adding the pom.xml fragment containing my Scala-maven-plugin fragment:

      <plugin>
        <!-- see http://davidb.github.com/scala-maven-plugin -->
        <groupId>net.alchim31.maven</groupId>
        <artifactId>scala-maven-plugin</artifactId>
        <version>3.3.1</version>
        <executions>
          <execution>
            <goals>
              <goal>compile</goal>
              <goal>testCompile</goal>
            </goals>
            <configuration>
              <args>
                <arg>-dependencyfile</arg>
                <arg>${project.build.directory}/.scala_dependencies</arg>
              </args>
              <jvmArgs>
                <jvmArg>-Xms512m</jvmArg>
                <jvmArg>-Xmx4096m</jvmArg>
              </jvmArgs>
            </configuration>
          </execution>
        </executions>
      </plugin>

Solution

You could :

de-recursive your code or use tail recursive

or increase the max stack size of the jvm used to run scalac via -Xss

      <jvmArgs>
        <jvmArg>-Xss4m</jvmArg>
        <jvmArg>-Xms512m</jvmArg>
        <jvmArg>-Xmx4096m</jvmArg>
      </jvmArgs>

I guess IDEA already increase the default max stack size (iirc 1024k in the 64-bit VM).
