无法将Maven项目导入IntelliJ IDEA

Question

无法将Maven项目导入IntelliJ IDEA

37

我在将任何Maven项目导入IntelliJ IDEA时遇到了问题。我像这样创建一个空的Maven项目：

$ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

我尝试在IDEA中打开项目（文件>打开项目，然后选择pom.xml）。进度框显示“读取pom.xml”几分钟，然后就消失了，没有打开项目。

查看IDEA日志，我看到一些连接超时异常，如下所示：

我正在使用最新版本的IDEA（11.1.3）和Maven（3.0.4）。有什么想法我做错了吗？

- del

可能是防火墙或其他网络问题，请参见http://youtrack.jetbrains.com/issue/IDEA-64132#comment=27-380070。 - CrazyCoder

@CrazyCoder - 谢谢！将 127.0.0.1 localhost 添加到 /etc/hosts 中解决了问题。如果您将您的评论发布为答案，我可以接受它作为解决方案。 - del

我正在使用社区版2017.2.1，遇到了同样的问题，我必须将Maven导入器的JDK版本更改为正确的版本（从1.6更改为1.8）才能使其正常工作。

- Zeus

我已经好几个月不能（更新存储库索引/下载源代码），必须在控制台中手动执行，现在谷歌把我带到了这篇文章，终于解决了！ - mickey

当我尝试下载我的依赖项源代码时，我遇到了同样的问题。根据您的答案所述，我通过更改JDK来解决了这个问题。 - Enrico Giurin

这可能是一个老的答案，但在2021年它为我解决了问题。我正在使用Windows 10上的Ultimate 2020.3。 - Jose Martinez

要在14.1.3 Ultimate中为我纠正这个问题，我需要在首选项（Preferences）> 构建、执行、部署（Build, Execution, Deployment）> 构建工具（Build Tools）> 导入（Importing）下的导入程序中添加

-Didea.maven3.use.compat.resolver

根据https://youtrack.jetbrains.com/issue/IDEA-140208上的错误提示。

- Najitaka

你救了我的一天。我一直在寻找解决方案。但是清理host文件和删除文件夹并没有帮助到我。所以添加这个代码片段让它工作了。 - dominic

太棒了。谢谢。 - Vahid

我在使用 IDEA 12 运行 Groovy 脚本时遇到了类似的问题。问题和 @CrazyCoder 所述的一样。解决方案基于 @kevinmrohr 的方法，只是更容易找到和设置。

为了解决问题，我编辑了位于 bin 目录下的 idea.exe.vmoptions（如果您使用的是 64 位版本，则是 idea64.exe.vmoptions），并添加了 -Djava.net.preferIPv4Stack=true。

重启 IDEA，一切都可以正常工作，没有任何问题。

@gjain，请查看您的IDEA文件夹。那里只有一个bin文件夹。 - krešimir

我曾经遇到过同样的问题。我不知道是什么原因导致它开始出现，但我知道我是如何解决它的。

通过查看 lsof -i -P，我发现 maven 远程服务器试图在 IPv6 上运行，显然 IntelliJ 无法与其通信。我不确定它以前是否在 IPv4 上运行，或者是否一直使用 IPv6 并且 mac 更新使其停止工作。

无论如何，我使用的解决方案是编辑 /Applications/IntelliJ IDEA 11.app/Contents/Info.plist 文件并向 java 进程添加 java.net.preferIPv4Stack 参数：

<key>java</key>
<dict>
  <key>Properties</key>
  <dict>
    <key>java.net.preferIPv4Stack</key>
    <string>true</string>
  </dict>
</dict>

我很希望能够提供更多关于为什么这件事发生的信息。

查找任何（最近安装的）可能会阻止RemoteMavenServer正确响应Intellij调用的应用程序。在我的情况下，原来是一款在线问责软件：x3watch。卸载它后，Intellij正常工作了。

我遇到了同样的问题。很抱歉，以上建议都没有对我起作用。实际上，当我从IntelliJ启动gradle项目时，在事件日志中出现了错误"Connection refused: connect"。我尝试了各种选项，如设置-Djava.net.preferIPv4Addresses=true、Windows热修复、安装ISA客户端、重新启动计算机、切换Java语言级别、禁用防火墙。但是没有什么帮助。

最后，在IntelliJ Idea中提供代理信息为我解决了问题。

查找在您的计算机上占用端口的进程。在Ubuntu Linux上，我执行了以下命令：

ps -ef | grep idea

注意到有一个Java进程正在运行类org.jetbrains.idea.maven.server.RemoteMavenServer

我记录了2772的pid并执行了

netstat -anp | grep 2772

我注意到pid 2772正在监听端口6942

我telnet到该端口：

telnet localhost 6942
Trying 127.0.0.1...  
Connected to localhost.
Escape character is '^]'.
/home/noahlz/.IdeaIC11/config/ home/noahlz/.IdeaIC11/system

因此，IntelliJ使用的Maven组件作为独立的服务器进程运行，IntelliJ通过套接字与其通信。您需要确定为什么IntelliJ无法在您的计算机上访问该服务器端口，即其他进程正在占用该端口和/或未向IntelliJ发送响应。

请注意，您计算机上的端口号可能不同。

我看不到正在运行的Maven服务器进程。当我运行ps -ef | grep idea时，我只看到

/usr/lib/jvm/jdk1.6.0_25//bin/java -Xms128m -Xmx800m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=64m -ea -Djb.vmOptionsFile=/usr/lib/idea-IC-117.798/bin/idea64.vmoptions -Xbootclasspath/a:../lib/boot.jar -Didea.paths.selector=IdeaIC11 -Djb.restart.code=88 com.intellij.idea.Main

。 - del

有些东西阻止了你的Maven服务器启动，答案很可能是日志中之前的错误。 - noahlz

我怀疑你是正确的，但我不知道如何找出是什么阻止了服务器的启动。在超时错误之前没有其他错误。我已经更新了问题，提供了我的整个日志。 - del

在我的情况下，以下行在 ~/.profile 中设置：

export _JAVA_OPTIONS="-Djava.net.preferIPv6Addresses=true"

我只是删除了这行并重新启动。之后正常工作。

我遇到了同样的问题，但是下面的答案解决了我的问题： Maven project won't compile after upgrade to Intellij 13.1 from 12

这个问题出现在我升级到IntelliJ 13.1.4之后，而在此之前一切都正常/按预期工作。

这是一个与网络和地址解析相关的常见问题。在某些情况下，localhost可能无法解析，因此需要使用

127.0.0.1 localhost

请确保在 /etc/hosts 文件中只有一个IP地址映射到localhost。

有些不同，但是在重建域配置文件后，我的/etc/hosts文件中有一个流氓条目。根据@CrazyCoder的答案编辑/etc/hosts文件并删除它可以解决问题，IntelliJ现在可以正确导入maven pom文件。 - Andrew Eells

同时也不能有任何其他IP指向本地主机！ - Macilias

@CrazyCoder请更新您的答案以包括Macilias的评论。必须删除重定向到本地主机的任何IP的其他映射。我也遇到了同样的问题并通过此解决了它。 - Sachin Jain

感谢@CrazyCoder，它节省了很多时间，我一直在尝试解决这个问题已经两周了。 - Nilesh Kikani

我无法在IntelliJ的Maven视图中正确导入Maven依赖项，因为我忘记排除本地代理中的localhost和127.0.0.1。 - user1767316

在我的情况下，我之前更改了JAVA_HOME路径，然后maven就会抛出这个错误。 - Amir Azizkhani
