无法将Maven项目导入IntelliJ IDEA

时间：2012-10-03 03:04:16

标签： maven intellij-idea

我在将任何Maven项目导入IntelliJ IDEA时遇到问题。我创建了一个空的Maven项目，如下所示：

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

然后我尝试在IDEA中打开项目（文件＆gt;打开项目，然后选择pom.xml）。一个表示“阅读pom.xml”的进度框显示几分钟，然后在没有打开项目的情况下消失。

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）。我有什么想法吗？

12 个答案:

答案 0 :(得分：70)

这是与网络和地址解析相关的常见问题。在某些情况下localhost可能无法解决，而且需要

127.0.0.1 localhost
在/etc/hosts文件中

。还要确保没有其他IP地址映射到localhost。

有关详细信息，请参阅相关YouTrack问题中的

See my comment。

答案 1 :(得分：10)

我使用社区版2017.2.1并且遇到了同样的问题，我不得不将maven导入程序的JDK版本更改为正确的版本（从1.6到1.8）以使其正常工作。

答案 2 :(得分：8)

要在14.1.3 Ultimate中为我纠正此问题，我必须添加

-Didea.maven3.use.compat.resolver

到“首选项”下的导入器的VM选项＆gt;构建，执行，部署＆gt;构建工具＆gt;导入

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

答案 3 :(得分：4)

我有一个类似的问题，用IDEA 12运行groovy脚本。问题与@CrazyCoder说的相同。解决方案基于@kevinmrohr所做的更容易找到和设置。

要解决此问题，我编辑了位于bin目录中的 idea.exe.vmoptions （ idea64.exe.vmoptions ，如果您使用的是64位版本）并添加了< EM> -Djava.net.preferIPv4Stack =真

重新启动IDEA，一切正常，没有任何问题。

答案 4 :(得分：2)

我有同样的问题。我不知道是什么导致它开始发生，我只知道我是如何修复它的。

我通过查看lsof -i -P发现maven远程服务器试图在IPv6上运行，显然IntelliJ无法在IPv6上对它说话。我不确定它是否曾经在IPv4上运行，有些东西导致它开始使用IPv6，或者它总是使用IPv6和mac更新以某种方式使它停止工作。

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

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

我真的希望我能提供更多关于为什么会发生这种情况的信息。

答案 5 :(得分：1)

找出您的计算机上正在保存该端口的进程。在Ubuntu Linux上，我执行了以下命令：

ps -ef | grep idea

注意到有一个运行类org.jetbrains.idea.maven.server.RemoteMavenServer

的Java进程

我注意到了2772的pid并执行了

netstat -anp | grep 2772

我注意到pid 2772正在侦听端口6942

我打算去那个港口：

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组件作为一个独特的服务器进程运行，IntelliJ通过套接字说话。您需要确定为什么IntelliJ无法访问您计算机上的服务器端口，即其他进程保留在该端口上和/或没有将响应发送回IntelliJ

请注意，您计算机上的端口号可能不同。

我遇到了同样的问题。对不起，上述建议均不适合我。事实上，当我从IntelliJ启动gradle项目时，我在事件日志中收到错误“连接被拒绝：连接”。我尝试了各种选项，如设置-Djava.net.preferIPv4Addresses = true，windows hot fix，安装ISA Client，重启机器，切换java lang级别，禁用防火墙。什么都没有帮助。

最后在IntelliJ Idea中提供代理信息对我来说很有用。

查找可能阻止RemoteMavenServer正确响应Intellij调用的任何（最近安装的）应用程序。就我而言，它原来是一个在线问责软件：x3watch。卸载后，Intellij开始正常工作。

答案 8 :(得分：1)

在我的情况下，以下行设置为〜/ .profile

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

我刚刚删除了线路并重新启动。之后工作正常

有同样的问题，但以下答案解决了我的问题： Maven project won't compile after upgrade to Intellij 13.1 from 12

问题本身在我更新到IntelliJ 13.1.4后发生，该补丁之前的所有工作正常/按预期工作。

我有类似的问题

MAC OS X

我做了什么：

  • 停用防火墙
  • 在intellij中设置代理（如本主题中所述）
  • 设置ipstack-flag

没有解决问题...

帮助什么

  • 使用Java 1.6启动intellij而不是java 1.8（在/ Applications / IntelliJ \ IDEA \ 14.app/Contents/Info.plist中定义）

奇怪

我在Linux Mint上遇到了同样的问题。尝试了一切，但没有任何帮助。原来我的etc / hosts文件已损坏并恢复工作。另一种解决方案是：https://www.digitalocean.com/community/questions/how-to-restore-etc-hosts-on-ubuntu-14-04
