【问题描述】：

我在 Hudson 有一个使用以下构建选项构建的 maven 项目：

构建经常失败并出现 OutOfMemoryError: Java heap space 但我不知道为什么。

失败看起来像这样：

有人知道如何阻止这种情况发生吗？

【解决方案1】：

我想知道这个 MAVEN_OPTS 是否有效。也许这个链接会有所帮助，它直接修改了 Maven 启动脚本。

当我在 Hudson 遇到自动构建问题时，我会首先尝试模拟构建环境并手动启动构建任务，以检查问题是否可以重现。通过这种方式，我可以将问题追溯到 Hudson 或 Maven。

毕竟，Hudson 就像一个自动化批处理系统。
