Maven: 内存溢出错误 - 堆空间

Question

问题： 我在运行mvn clean install -DskipTest时出现了以下错误信息。

[ERROR] The system is out of resources.
[ERROR] Consult the following stack trace for details.
[ERROR] java.lang.OutOfMemoryError: Java heap space

更多信息：

• 操作系统：OS X（16 GB RAM）

• Java配置：位于〜/ Libraries / Preferences / IntelliJIdea13 / idea.vmoptins和Applications / IntelliJ \ Idea \ 13.app / bin / idea.vmoptions

  -Xms256m -Xmx2048m -XX：MaxPermSize = 1024m -XX：ReservedCodeCacheSize = 256m -XX：+ UseCompressedOops

• MAVEN_OPTS： export MAVEN_OPTS ="-Xmx2048M -XX：PermSize = 92M -XX：MaxPermSize = 384M"位于〜/ .bash_profile 中

• Intellij Idea Maven opts： -xms256m -xmx2048 -XX：MaxPermSize = 1024M 。我设置它们在默认设置 - > MAven - > Runner - > VM Options

问题： 如何解决？

请使用“-e”运行它并发布错误堆栈。 - jmj

它在哪个阶段耗尽了内存？是Maven编译器插件还是测试。 - ssedano

@ssedano在其中一个模块上工作。这意味着已经构建了几个子模块，但在下一个模块中失败了。 - VB_

请执行 $ echo $MAVEN_OPTS 以确保其已加载。如果没有，请尝试运行 $ MAVEN_OPTS="-xms256m -xmx2048 -XX:MaxPermSize=1024M" mvn clean install -DskipTest - ssedano

@ssedano echo $MAVEN_OPTS 返回 -Xmx2048M -XX:PermSize=92M -XX:MaxPermSize=384M。 - VB_

Answer 1

如果根据上面的注释，Java编译器插件会耗尽内存，为了解决这个问题，您需要为Java编译器插件提供更多的内存。您可以在pom.xml文件中添加以下代码：

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <fork>true</fork>
          <meminitial>512m</meminitial>
          <maxmem>1048m</maxmem>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>
