When I do a maven dependency resolution, its taking forever to get it through and this is what I get:
当我进行 maven 依赖解析时，它需要很长时间才能通过，这就是我得到的：
And it sticks here forever.
它永远粘在这里。
Here are my maven settings:
这是我的 Maven 设置：
I followed steps given in thisSO answer.
我遵循了这个SO 答案中给出的步骤。
Please let me know where am I doing wrong and how do I get rid of it.
请让我知道我做错了什么以及如何摆脱它。

If this should help, I am trying to run this code: https://github.com/hmkcode/Android/tree/master/java-post-gcm
如果这有帮助，我正在尝试运行此代码：https: //github.com/hmkcode/Android/tree/master/java-post-gcm
I am not sure whether its an issue with the pom.xml itself. Perhaps if someone is able to have it working on his IDE, it may be concluded that its an issue with my specific IDE config.
我不确定它是否是 pom.xml 本身的问题。也许如果有人能够在他的 IDE 上使用它，那么可能会得出结论，这是我的特定 IDE 配置的问题。

If this is an issue very specific to intellij, I would suggest do the following steps You can try running mvn clean install.(Depending on your network speed it will pull every dependency)
如果这是一个非常特定于 intellij 的问题，我建议执行以下步骤您可以尝试运行 mvn clean install。（根据您的网络速度，它将拉取每个依赖项）
Change intellij settings in Preferences->build,execution,deployment->maven->Maven home directory->{now change this to point to your mvn home rather than bundled mvn}
在 Preferences->build,execution,deployment->maven->Maven home directory->{now 将其更改为指向您的 mvn home 而不是捆绑的 mvn} 中的更改 Intellij 设置
mvn -v in command line should give you the maven home path. Now it won't try to download dependencies again.
命令行中的 mvn -v 应该为您提供 maven 主路径。现在它不会再次尝试下载依赖项。

File | Settings | Build, Execution, Deployment | Build Tools | Maven | Threads (-T option) | 16 (or however many threads you want to try)
档案 | 设置 | 构建、执行、部署 | 构建工具 | 马文 | 线程（-T 选项）| 16 个（或者你想尝试多少个线程）
mvn compile -T 8
I had the same issue. Maven was taking an hour in IntelliJ and also running from the command line. Using the -T parameter you can tell Maven to use more threads to download artifacts simultaneously. Takes only about 15 minutes now.
我遇到过同样的问题。Maven 在 IntelliJ 中花费了一个小时，并且还从命令行运行。使用 -T 参数可以告诉 Maven 使用更多线程同时下载工件。现在只需要大约 15 分钟。
Don't use bundled mvn. Point "Maven home directory" to the path on your file system.
不要使用捆绑的 mvn。将“Maven 主目录”指向文件系统上的路径。
After you're done building. Check "Work offline". This stops mvn from searching remote websites each time you build. Uncheck when you update your POM file so it can search for the changes.
搭建完成后。选中“离线工作”。这会阻止 mvn 在您每次构建时搜索远程网站。在更新 POM 文件时取消选中，以便它可以搜索更改。
You can also skip tests. This is evertyhing from the command line.
您也可以跳过测试。这是来自命令行的一切。
mvn clean install -T 50 -o -DskipTests
