Can not download sources with Intellij Idea community 12.1.4 and maven 3.0.5
提问by Cherry
I click "download sources and documentation" in Intellij Idea Community Edition 12.1.4 and get error that sources can not be downloaded. But when I try:
我在 Intellij Idea Community Edition 12.1.4 中单击“下载源代码和文档”并收到无法下载源代码的错误消息。但是当我尝试：
mvn dependency:sources
All sources are downloaded.
下载所有源。
What is the problem?
问题是什么？
P.S.I have checked that Idea use the same maven that use in console. There are not any "off line" mode buttons triggered in Idea.
PS我已经检查过 Idea 使用与控制台中使用的相同的 Maven。Idea 中没有触发任何“离线”模式按钮。

I had the same issue with IntelliJ IDEA 2016.1.3and Maven 3.2.1. No solution mentioned here was working. In my case a newer Maven version fixed the issue. With Maven 3.3.9IDEA can now download the sources.
我在 IntelliJ IDEA 2016.1.3和Maven 3.2.1 上遇到了同样的问题。这里提到的解决方案都没有奏效。就我而言，较新的 Maven 版本解决了该问题。随着Maven 3.3.9IDEA 现在可以下载源代码。

anything's already in the former answers...
以前的答案中已经有任何内容......
- download sources in your repo
mvn dependency:sources - F4 on the class you want to check the sources out
- locate the source jar in your local repository
- 在你的仓库中下载源代码
mvn dependency:sources - F4 在您要查看来源的课程上
- 在本地存储库中找到源 jar
maybe it is not a full IDE solution, but hope it solves your issue
也许它不是一个完整的 IDE 解决方案，但希望它能解决您的问题

Had the same issue with IntelliJ 2016.2.4. As user526177 posted udating the Maven version fixes it but for my needs switching to the bundled Maven 2 was just fine and fixed the issue.
IntelliJ 2016.2.4 也有同样的问题。正如 user526177 发布的 udating Maven 版本修复了它，但为了我的需要，切换到捆绑的 Maven 2 就好了并解决了这个问题。

I use IDEA 2017.1.3, I just change the Maven home directory option(Preferences -> Build, Execution,Deployment -> Build Tools -> Maven -> Maven home directory) of default Maven 3 to Maven 2, I believe it's the same solution for newer version of IDEA just like the selected answer. And it works for me.
我使用 IDEA 2017.1.3，我只是将默认 Maven 3 的 Maven 主目录选项（首选项 -> 构建、执行、部署 -> 构建工具 -> Maven -> Maven 主目录）更改为 Maven 2，我相信它是相同的新版 IDEA 的解决方案就像所选答案一样。它对我有用。

I had this issue, and sources weren't being downloaded since I needed credentials from my project's specificsettings.xml.
我遇到了这个问题，并且没有下载源代码，因为我需要来自项目特定settings.xml.
To fix (Intellij 2018.1.2):
修复（Intellij 2018.1.2）：
File -> Settings -> Build, Execution, Deployment -> Maven
文件 -> 设置 -> 构建、执行、部署 -> Maven
and provide the appropriate settings.xmlin the 'User settings file' section
并settings.xml在“用户设置文件”部分提供适当的
