我在 Mac Yosemite 上使用 Maven3.3.3和 Java8,我有一个多模块的项目。
<modules>
<module>first-module</module>
<module>my-module</module>
…
</modules>
当我使用“ mvn clean install”构建我的一个子模块时,例如,从上面的“ my-module”,这个构建尝试从我在 ~/中定义的远程存储库下载子模块构件。M2/setings.xml 文件。输出如下
[INFO]

如何强制 Maven 检查我的本地 ~/。在尝试从远程存储库下载之前先下载 m2/存储库?下面是我在 ~/中定义远程存储库的地方。M2/setings.xml 文件..。

编辑: 对于回答说当工件不在时下载发生,下面是终端输出,我证明文件在我的回购中,但 Maven 正试图下载它..。
