我在一个Linux机器上安装了Intellij IDEA社区,需要使用经过身份验证的代理来访问Internet.我在包装盒上有一个系统范围的代理,我在〜/ .m2/settings.xml中配置了代理.当我从命令行运行时,Maven正确使用代理.

我在Intellij中配置了相同的代理,它为我提供了正确的插件列表.但是当我尝试使用Intellij与Maven存储库同步时,我会继续这样做:

[WARNING] Unable to get resource 'org.codehaus.mojo:hibernate3-maven-plugin:pom:2.2' 
from  repository restlet (http://maven.restlet.org): Authorization failed: Not   
authorized by proxy.

我去了Settings-> Maven并将代理信息作为属性输入,但是没有用.我可以通过查看Intellij正在阅读我的〜./ m2/settings.xml的那些设置来查看,因为它知道我的本地仓库在哪里(它在非标准位置).

任何人都知道如何让这个工作？

我在将任何Maven项目导入IntelliJ IDEA时遇到问题.我创建一个空的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>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:

➠IntelliJ中的哪些功能充当接收传入连接的服务器？

首次运行IntelliJ 2017.1.1时,我收到一个对话框,询问传入网络连接的权限.

您是否希望应用程序"java"接受传入的网络连接？

单击"拒绝"可能会限制应用程序的行为.可以在"安全和隐私"首选项的"防火墙"面板中更改此设置.

[否认允许]

单击Maven选项卡时,在New Project向导中全新安装IntelliJ 2017.2 Ultimate Edition时出现的对话框示例.

为什么IntelliJ会导致此提示？运行NetBeans时我没有遇到这样的事件.

否认或接受的影响究竟是什么？我担心让Java进程接受外部网络连接,因为这样做会带来严重的安全风险.

可能与:

• 问题:如何将IntelliJ IDEA随机开放端口仅绑定到localhost？
• 问题IDEA-175889:在某些配置中,IDE会在通配符接口上打开随机端口

这个问题不是关于消息的来源.源是Apple macOS 应用级防火墙.您可以允许或阻止应用程序侦听传入的网络连接.允许这是一个安全风险.

IntelliJ要求添加到允许侦听传入消息的应用程序列表中.我的问题是,"为什么IntelliJ需要接受传入的网络连接？".

升级后,我的代码不再编译.来自作为maven依赖项包含的库的导入显示编译问题,无法解析符号.我已经使缓存失效并重新启动了Intellij.我已经清除了.m2/repository并在依赖项中观察了Intellij repull.拉入依赖项似乎工作正常,但然后无法加载是我的猜测.

在我的Idea日志中,我看到以下例外情况:

我想切换到IntelliJ for forge modding(minecraft).当我做他们在网上做的事情时,我得到了一个maven错误......

            Unindexed remote maven repositories found. Disable...
            The following repositories used in your gradle projects were not indexed yet: 
            http://files.minecraftforge.net/maven
            If you want to use dependency completion for these repositories artifacts,
            Open Repositories List, select required repositories and press "Update" button

当我点击更新,它加载半秒然后再次给出相同的错误...我在互联网上搜索,没有人似乎有我的问题...请帮助吗？

也许你可以帮助我,当我在Intellij Idea 13打开我的项目时,我遇到了一个奇怪的apache maven的问题.当项目打开时,我在外部库部分没有库.在diff的模块的所有pom.xml文件中,我看到错误"无法重新连接".

我试图使无效的缓存/重启想法,尝试使用Maven Reimport,但问题仍然存在.但是如果我做mvn clean install,并部署我的项目一切正常.我使用Maven 3.2.3.和Java 1.8.

我正在做一些测试工作,需要使用JUnit中我不熟悉的功能.为了更好地理解这些功能,我希望能够在我的项目中查看IntelliJ内部的JUnit源代码.

这个项目使用Maven.我对pom.xml文件中列出的jUnit有以下依赖关系:

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.10</version>
</dependency>

当我在命令行上运行"mvn clean install"时,jUnit源从我公司的Maven存储库下载到我的本地Maven存储库(.m2目录).然后该项目编译并运行没有问题.

右键单击pom.xml文件并选择Maven-> Reimport后,我可以看到jUnit的类,源和javadoc也出现在IntelliJ的库设置中:

但是,当我尝试在IntelliJ中打开一个jUnit类文件并单击"下载源"链接时,我看到:

似乎IntelliJ应该在本地找到这些来源.即使它确实必须从我公司的存储库下载它们,我也相信它应该在那里找到它们,因为那是我本地存储库中的junit-4.10-sources.jar文件最初来自的地方.

什么可能使IntelliJ无法加载它已经知道的JAR文件中的源代码？
