hudson 中的 java OutOfMemoryError

Question

我在 hudson 中运行 pmd、findbugs 时收到以下错误。

FATAL: Java heap space  
java.lang.OutOfMemoryError: Java heap space

我已经为 pmd 指定了 jvmargs，findbugs 并将 ant_opts 设置为 1024M。

Answer 1

如果您在 Windows 中，则必须编辑 hudson.xml 文件以包含 java 参数
-Xmx1024m，但是如果您在 *nix 环境中，则必须运行命令

export JAVA_OPTS=-Xmx1024m

或更合理的内存大小。
