今天打包項目出現以下錯誤：
[ERROR] Unknown lifecycle phase “mvn”. You must specify a valid lifecycle phase or a goal in the format : or :[:]:. 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]
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/LifecyclePhaseNotFoundException
通過最後一行提示信息找到：
根據提示信息就有了下面解決方案：
mvn install --> mvn compiler:compile --> mvn org.apache.maven.plugins:maven-compiler-plugin:compile -->mvn org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile
成功
