执行 Maven 并行构建时的线程安全警告

Question

我正在运行 Maven 并行构建。我收到了一些警告。

[WARNING] *****************************************************************
[WARNING] * Your build is requesting parallel execution, but project      *
[WARNING] * contains the following plugin(s) that are not marked as       *
[WARNING] * @threadSafe to support parallel building.                     *
[WARNING] * While this /may/ work fine, please look for plugin updates    *

[WARNING] ****************************************************************

构建成功。谁能告诉我以下插件的哪个版本是线程安全的。

我可以忽略这个吗？

Answer 1

org.apache.maven.plugins:maven-clean-plugin:2.5 和 org.codehaus.mojo:cobertura-maven-plugin:2.5.2 都是线程安全的（来自 https://maven.apache.org/plugins/）

大多数情况下，此警告无需担心，但如果您使用并行构建功能，我建议您为插件使用线程安全版本。
