如何在Maven上解除项目

Question

我正在尝试将文件安装到我的本地Maven存储库(按照https://gist.github.com/4211293中的步骤),但是,我总是收到以下错误消息:

我不确定错误是否因为正在跳过google-play-services,如果您这么认为,请帮助解除它.

Answer 1

据我所知,一个项目只有当它依赖的其他模块无法构建时才会被"禁止".这就是"先前失败"的含义.你需要回到第一次失败并修复它.

Answer 2

当您尝试多次将相同的发布版本（不是 *-SNAPSHOT）部署到存储库时，此错误消息出现在 maven 中。这通常是禁止的，以防止不可预测的构建。如果你想多次部署同一个版本，它需要是 -SNAPSHOT 版本。

我想在你的情况下也会发生同样的事情，当你安装文件并且文件已经存在并且不是 -SNAPSHOT 版本时。Maven 然后得出结论，安装将在任何重复尝试时再次失败，因此将其标记为“禁止”。

那么解决方案是将工件版本更改为 -SNAPSHOT 版本或增加到下一个发布版本 - 然后再次构建。

Answer 3

问题解决了。该错误与-Dfile参数有关，因为它似乎不接受相对路径。

PS：我遇到的另一个问题是我一直在使用PowerShell运行maven命令，但是存在某种不兼容性。
