无法在项目 nextrtc-signaling-serverrror 上执行目标 org.codehaus.mojo:exec-maven-plugin:1.5.0:java (default-cli)

Question

我测试了 Java 的开源 nextrtc-signaling-server。但是我遇到了构建 Maven 的问题。我希望这个问题得到解决。

我的控制台日志。

我在 "clean package exec: Java"（Maven 目标）

处构建了这个源代码

我需要做什么？我真的很想修复它。

Answer 1

您可以使用以下命令构建 nextrtc-signaling-server 项目 (https://github.com/mslosarz/nextrtc-signaling-server)。

mvn clean package

如果项目中有一个主 class（例如 MySampleApplication.java）和包（例如 com.sample.my），那么您可以运行使用下面的命令.

mvn exec:java -Dexec.mainClass="com.sample.my.MySampleApplication"

如果您想使用 "nextrtc-signaling-server" 开发新应用程序，请在您的 maven 项目中添加以下 maven 依赖项。请参考https://nextrtc.org/archives/85

<dependency>
   <groupId>org.nextrtc.signalingserver</groupId>
   <artifactId>nextrtc-signaling-server</artifactId>
   <version>0.0.3</version>
</dependency>

Answer 2

您无需做太多工作即可解决此问题。只需转到位于服务下的 Maven 存储库，然后右键单击并 select 添加存储库，然后添加存储库 name.In 在这种情况下它应该是 org.codehaus... 看看效果如何
