Spring Boot示例在eclipse中抛出MojoExecutionException

甄永年
2023-03-14

我正在使用本教程学习Spring Security性和AngularJS。本教程的第一部分指定了对pom.xml的非常具体的更改。但是当我添加这些pom.xml更改时，会出现错误。

Plugin execution not covered by lifecycle configuration:  ro.isdc.wro4j:wro4j-maven-plugin:1.7.6:run (execution: default, phase: generate-resources)

    <execution>  <!-- this line throws the compilation error in eclipse -->
          <phase>generate-resources</phase>
          <goals>
            <goal>run</goal>
          </goals>
        </execution>

当我试图通过在CentOS终端上运行mvn spring-boot:run来绕过eclipse时，会出现以下堆栈跟踪结果：

注在上面的堆栈跟踪中有一个地址已经在使用错误。起初，我认为该错误可能是由于重新启动程序时端口8080冲突造成的，但即使在运行shutdown.sh和startup.sh以重新启动Tomcat时，问题仍然存在。另外，请注意，堆栈跟踪末尾的消息表明pom.xml中的某个插件可能导致了这个问题，您可以通过单击此链接来验证这一点。

当您执行MVN spring-boot:run时，它有自己的嵌入式Tomcat，因此它不需要单独的Tomcat实例来运行，因此这两个Tomcat之间存在冲突。

您只需运行:shutdown.sh，然后按此方式运行，然后再试一次。
