运行Maven是报错：No goals have been specified for this build .

 

运行Maven的时候， pom.xml --> Run As --> Maven build    时报错如下，

Java代码  

 No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

 

 

 pom.xml文件<build>标签里面加上<defaultGoal>compile</defaultGoal>即可
 <build>    <defaultGoal>compile</defaultGoal>   </build>
