Java 由于API不兼容，Maven war插件3.0.0出现问题

java eclipse maven jsf

Java 由于API不兼容，Maven war插件3.0.0出现问题,java,eclipse,maven,jsf,maven-war-plugin,Java,Eclipse,Maven,Jsf,Maven War Plugin,我将学习这个JSF教程。 我想我已经完成了那里写的所有工作（下载所有需要的软件，设置环境和变量路径等等），但是我无法解决Maven war插件的编译问题。我已经阅读了很多问题和可能的解决方案，我想我已经尝试了大部分建议的组合（mvn清理然后安装，设置正确的jdk版本，指向jdk目录而不是jde，删除.m2存储库，强制升级项目，等等）。所以，我在这里，也许描述我的具体问题将有助于理解如何解决它 mvn清洁安装的输出： [ERROR] Failed to execute goal org.apach

Maven和Java的版本非常流行，但war插件的版本却不是。尝试使用最新版本，即per是3.3.1（在原始答案时）。

Maven和Java的版本非常新，但war插件版本不是。尝试使用最新版本，即per是3.3.1。哦，太简单了。。非常感谢。精彩的。我补充说，作为一个答案，请接受它，让未来的人们知道该怎么做。
