java.lang.OutOfMemoryError：Maven中的Java堆空间
java.lang.OutOfMemoryError：Maven中的Java堆空间
提问于 2018-03-01 00:22:19
当我运行maven测试时，java.lang.OutOfMemoryError就会发生。我用谷歌搜索解决方案，并试图export MAVEN_OPTS=-Xmx1024m，但没有用。任何人都知道这个问题的其他解决方案，我正在使用maven 3.0。
当运行“mvn test-e”时，将错误消息粘贴在这里。

当我运行maven测试时，发生java.lang.OutOfMemoryError。我谷歌它的解决方案，并试图导出MAVEN_OPTS = -Xmx1024m，但它没有奏效。
使用设置Xmx选项MAVEN_OPTS确实有效，它确实配置了用于启动Maven的JVM。话虽如此，默认情况下，maven-surefire插件默认会分配一个新的JVM，MAVEN_OPTS因此您的系统无法通过。
要配置maven-surefire插件使用的JVM的大小，您需要：
在后面的例子中，是这样的：
<configuration>
<argLine>-Xmx1024m</argLine>
</configuration>
但是我不得不说，我倾向于在这里同意Stephen的观点，您的测试很有可能出了问题，我不确定提供更多内存是解决问题的正确解决方案。

对于Maven的新手(像我一样)，下面是POM的构建部分中的整个配置.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19</version>
<configuration>
<argLine>-Xmx1024m</argLine>
</configuration>
</plugin>
</plugins>
</build>页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
