gradle - Scaladocs构建失败kafka

Question

我正在尝试使用gradle从源代码构建Apache kafka，如here所述，但我无法获取scaladocs。以下是相同的错误日志:

 == Expanded type of tree ==

ConstantType(value = Constant(kafka.utils.timer.TimerTaskList))

uncaught exception during compilation: java.io.IOException
File name too long
two errors found
:core:compileScala FAILED
:core:compileScala (Thread[Daemon worker,5,main]) completed. Took 1 mins 4.416 secs.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':core:compileScala'.
> Compilation failed

* Try:
Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.

BUILD FAILED

尽管我怀疑这是内存问题，但我看不到有任何更改的地方。我在这里尝试编辑:

tasks.withType(ScalaCompile) {
    scalaCompileOptions.useAnt = false

    configure(scalaCompileOptions.forkOptions) {
      memoryMaximumSize = '1g'
      jvmArgs = ['-XX:MaxPermSize=512m']
    }
  }
}

但这没有帮助。

是的，这可能与Gradle内存设置有关。您可以通过设置环境变量set GRADLE_OPTS=-Xmx1024m(Windows)来增加Gradle堆，它可能会更好。
