运行 mvn install 并并行运行 tomcat 插件答案

【问题标题】：Running mvn install with running tomcat plugin parallel运行 mvn install 并并行运行 tomcat 插件

【问题描述】：

项目中有单元测试和前端html测试需要运行webserver。为了mvn install 顺利通过，我需要这两种测试都顺利通过。我使用嵌入式 tomcat 服务器，它是通过 maven 的 tomcat 插件启动的：

mvn tomcat7:run

所以，我启动了 tomcat（我的前端 html 测试需要它），然后尝试在命令行中启动：mvn install，但得到以下错误：

D:\PROJECTS\SpringMvcExample>mvn install
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:741]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

同时，当tomcat启动时，我可以通过Intellij Idea插件为maven运行mvn install，它运行良好，没有任何错误。

我的问题是如何配置才能在命令行中启动maven？

这是一个maven多模块项目，这里是web模块的pom.xml：

【问题讨论】：

请附上您的pom.xml。

标签： java maven configuration embedded-tomcat-7

【解决方案1】：

尝试将tomcat run/shutdown绑定到合适的<execution>阶段：

<phase>pre-integration-test</phase>
<goals>
  <goal>run</goal>
</goals>

和

<phase>post-integration-test</phase>
<goals>
  <goal>shutdown</goal>
</goals>

这样配置你不应该手动启动tomcat（即mvn tomcat7:run）。它应该在测试之前自动运行并在测试之后关闭。
