使用IntelliJ IDEA导入Maven项目（Android）

Question

如果我使用带有Maven集成的IDE（IntelliJ IDEA）来导入Maven项目（Android），我还需要在命令行上运行mvn install来构建项目吗？ 或者应该在项目导入向导期间由IntelliJ完成所有操作？

编辑 ：我的问题是，在将项目导入IntelliJ后，当我打开我的库时，许多Maven库链接到错误的源和javadoc。 他们获取源和javadocs的文件夹确实存在，但引用的特定javadoc.jar或sources.jar文件不存在于该文件夹中。

所以我想我的Maven导入做错了 - 我只使用IntelliJ向导来做。 奇怪的是，该项目仍然编译并运行良好，这个问题的唯一“症状”是空的javadocs。

编辑（11月9日）：我尝试了@JJF建议的方法，虽然它确实下载了丢失的javadocs和源文件，但它们添加了一个'.lastUpdated'后缀。 为什么会这样？

另外，我手动重命名了javadocs，当它在Libraries窗口中清除时，当我回到我的项目时，我的内联文档（鼠标悬停）仍然会显示空文档（这是最初引发我这个问题的问题，我在这里创建了一个不同的线程）。 也许我可能在我的SDK文档路径中做错了什么？

运行@ Nick78描述的过程会产生以下错误：

Answer 1

从命令行运行

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc

这将下载任何缺少的源和Javadocs。 请参阅从Maven存储库获取源JAR

还要使用IntelliJ与运行mvn install来构建项目：无论何时运行或调试应用程序，IntelliJ都会编译源文件。 您不需要运行maven来编译源代码。 如果你想在IntelliJ中打包或安装项目，那么转到Maven Projects工具窗口并展开Life Cycle节点或Plugins节点，你可以通过双击你想要运行的任何目标来运行Maven目标。

如果右键单击其中一个目标，则可以为该目标创建运行配置，以便从运行配置下拉列表中运行。

Answer 2

首先要确保在设置（ Top menu > File > Settings > Build, Execution, Deployment > Build Tools > Maven ）中，IntelliJ指向与M2_HOME中定义的Maven安装中定义的相同的Maven存储库。 这通常是（在Windows中） C:\\Users\\Username\\.m2\\repository 。 然后在控制台中转到pom.xml所在的目录并输入： mvn idea:idea （将创建或重新创建IntelliJ项目文件）。 在IntelliJ中，请确保选中Top menu > View > Tool Buttons 。 在IntelliJ窗口的边界某处有一个名为Maven Projects的按钮单击它。 在打开的对话框中，单击绿色+并添加您的pom.xml 。 之后，单击maven对话框左上角的重新导入按钮（蓝色指针圈）。 然后在同一对话框中展开your project > Lifecycle 。 按住ctrl并选择clean并install 。 单击带有lighning（跳过测试）的蓝色圆圈，然后单击播放按钮。 也许再做一次重新进口（蓝色指针圈）。
