如何解决Sonarqube java.lang.OutOfMemoryError: Java heap space

Question

我正在使用 Sonarqube 社区版。我收到以下错误，

Exception in thread "LOG_FLUSHER" Exception in thread "CHECKPOINT_WRITER" java.lang.OutOfMemoryError: Java heap space

我已经更改了 sonar.properties 中的大小，但我仍然面临同样的问题。如何解决这个问题。

sonar.web.javaOpts=-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError
sonar.ce.javaOpts =-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError 
sonar.search.javaOpts=-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError

Answer 1

您更改的是将内存分配给 SonarQube 本身的设置。

您需要更改的是为分析过程分配内存的设置。你还没有说你使用的是哪个分析仪，所以细节会有所不同，但是

• 用于 SonarQube 扫描仪 export SONAR_SCANNER_OPTS="-Xmx512m"
• 适用于 Maven 的 SonarQube 扫描仪 export MAVEN_OPTS="-Xmx512m"
