java - 错误 : Path must include project and resource name:/(org. apache.maven.plugins :maven-jar-plugin:2. 4:jar:default-jar:package)

Question

当我尝试将 Intellij 创建的项目导入 Eclipse 时，出现了标题错误，并且在导入后，每当我尝试保存文件更新或更新项目时，也会提示相同的错误。我搜索了很多地方，发现这个问题实际上在互联网上很常见，但据我所知，没有一个有效的解决方案。所以我必须亲自问这个问题，以获得更多的关注——也许是来自真正了解问题并且也有解决方案的人。以下是有关我的工作环境的一些必要信息:Eclipse Neon、Windows 7，以及完整的堆栈跟踪:

Path must include project and resource name: / (org.apache.maven.plugins:maven-jar-plugin:2.4:jar:default-jar:package)

Answer 1

我通过将父 pom.xml 中的绝对路径更改为相对路径解决了该问题。绝对路径无效的原因是Eclipse不允许在项目之外设置输出目录。引用:https://stackoverflow.com/a/27562184/4357087
