java - Maven GWT编译器编译两次？

标签 java maven gwt

我是 Maven pom 配置的新手，并且被这种情况困扰。我已经通过谷歌搜索和“stackoverflowed”寻找答案，但我看到的解决方案对我不起作用。

我在 Eclipse Mars 中有以下项目结构:

parent project(folder)
....pom.xml
....ear project(folder)
.......pom.xml
....rest project(war)(folder)
........pom.xml
....front project(war)(folder)
........pom.xml

当我执行 maven clean install -e wildfly:deploy 时，我将客户端(前端)项目编译了两次。我做错了什么？

其pom.xml如下:

如果您需要更多信息，请询问。我真的被这个问题困扰了，而且我很确定这完全是菜鸟的失败。

最佳答案

最后通过更改执行maven命令解决了，我的意思是:

我通过 Eclipse 启动 Maven，如下所示:

mvn clean install -e wildfly:deploy

现在，改变这个之后..

mvn clean -e wildfly:deploy

根据documentation ，此插件中的“部署”阶段调用“打包”阶段:

Invokes the execution of the lifecycle phase package prior to executing itself.

另一个解决方案，使用第一个 Maven 命令行是:

mvn clean install -e wildfly:deploy-only

这避免了“打包”阶段。更多信息 aboy
