Scaladocs 构建失败 kafka

Question

我正在尝试使用 gradle 按照 here 的解释从源代码构建 Apache kafka，但我无法构建 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

虽然我怀疑这是内存问题，但我没有看到任何改变它的地方。我尝试在这里编辑：

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

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

但这并没有帮助。

Answer 1

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

Answer 2

错误是由于我的主文件夹被加密造成的。 kafka 似乎无法安装在加密文件夹中。我不得不重新安装 ubuntu 来解决这个问题。别无选择。
