java - OutOfMemory - Sonar 无法分析项目源代码，也找不到问题

Question

我正在 IntelliJ Idea 的 Java 项目中运行插件 SonarLint。

当我请求整个项目的代码分析时，我收到以下消息:

SonarLint 分析失败:Java 堆空间

以下是日志:

如何增加内存？

Answer 1

Eclipse:运行 --> 运行配置 --> 然后选择maven build 下的项目 --> 然后选择选项卡“JRE"--> 然后输入 -Xmx1024m。

运行 --> 运行配置 --> 选择“JRE”选项卡 --> 然后输入-Xmx1024m

我建议您使用profiler检查您需要多少内存，以免分配太多内存。

我错过了 IntelliJ Idea:

您可以获取信息here

请确保您在正确的位置增加了堆。您需要单击 IDEA 的 Ant 工具窗口中的“属性”按钮并编辑“最大堆大小 (Mb)”字段。
