Question

我最近决定尝试将我的Maven项目用作另一个项目的依赖项。我构建了项目并将其安装到我的本地存储库：

The snapshot in my local repository

然后我设置另一个Maven项目来使用这个依赖项（参见依赖项块中的第一个依赖项）：

有谁知道为什么会这样？我很高兴 - 并且能够和我一起管理Maven - 使用我的Eclipse版本，所以宁愿不使用m2eclipse。

干杯。

Answer 1

如果引用的项目存在于同一个根目录下，它将添加对依赖项目的引用，而不是对快照jar文件的依赖项。有关详细信息，请访问此URL。

Answer 2

你有没有尝试过mvn eclipse：clean然后是mvn eclipse：eclipse。此外，这可能是显而易见的，但如果您在eclipse中查看它，则必须刷新文件。

mvn eclipse：eclipse没有将SNAPSHOT JAR添加到classpath
