Maven 我如何清除此地址，使其不再是“；已在使用中；？

我正在尝试设置Dashbuilder。我已经遵循了说明，但有一些问题，现在我只剩下一个问题（我想）。我进去的时候

`mvn jetty:run -P h2,jetty`

我得到以下结果：

`[ERROR] Failed to execute goal org.eclipse.jetty:jetty-maven-plugin:9.3.9.v20160517:run (default-cli) on project dashboard-builder: Failure: Address already in use -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.eclipse.jetty:jetty-maven-plugin:9.3.9.v20160517:run (default-cli) on project dashboard-builder: Failure

以下是MVN的输出--版本：

我不确定我做错了什么。

另一个进程已经在使用您尝试将套接字绑定到的端口

---

例如，您可以使用以下命令查找哪个进程正在使用该端口：

netstat-tulpn

是分配给运行jetty的端口可能被其他进程使用

---

您可以使用“sudo fuser-n tcp-k 8000”清除端口，其中8000是用于运行jetty的端口号。

您尝试在其他端口上运行jetty。你必须弄清楚是什么，为什么。
