Jenkins 中的堆空间问题答案

【问题标题】：Heap Space issue in JenkinsJenkins 中的堆空间问题
【发布时间】：2023-04-03 15:15:02
【问题描述】：

在 Jenkins 中，我们遇到以下错误。它显示Out Of Memory Error。我将堆大小从 256 增加到 1024，但这仍然不起作用。当我将堆大小从 1024 增加到 2048 时，Jenkins 服务不起作用。我在 Jenkins.xml 文件中进行了所有这些更改。

BUILD FAILED

【解决方案1】：

您执行 ant 构建。因此，您必须增加 ant build 的堆，而不是 jenkins 服务器的堆。

看看How to use the `Java Options` in jenkins ant build tool to set ANT_OPTS
