为什么Maven跳过我的自定义生成源执行？

本文介绍了为什么Maven跳过我的自定义生成源执行？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我添加了执行 .thrift - > .java 作为generate-sources阶段的一部分，使用 maven-antrun-plugin 。但是当我输入 mvn generate-sources 时，Maven会跳过这个执行。

I added executions for .thrift -> .java as part of the generate-sources phase, using maven-antrun-plugin. But when I enter mvn generate-sources, Maven skips right over this execution.

这个？

pom.xml：
