# Eclipse导入maven项目时，Pom.xml文件报错处理方法 #

导入maven项目，FIle→Import→Existing Maven Projects→找到自己想要导入的文件目录→Finish。项目就导入完成啦。接着就遇上了各种报错！！

**一、Pom.xml文件第一次报错**

*CoreException: Could not get the value for parameter compilerId for plugin execution default-testCompile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.apache.maven:maven-plugin-api:jar:2.0.9, org.apache.maven:maven-artifact:jar:2.0.9, org.apache.maven:maven-core:jar:2.0.9: Failure to transfer org.apache.maven:maven-plugin-api:jar:2.0.9 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven:maven-plugin-api:jar:2.0.9 from/to central (https://repo.maven.apache.org/maven2): connect timed out。*

**解决方法：**

这是因为网络原因，导致文件没有下载完成。

在电脑中搜索xxx.jar.lastUpdated，并将其都删除即可，具体步骤如下：

1）找到 \{user\}/.m2/repository

2）搜索“.lastupdated”。（如果不记得对应的.m2位置，可以全计算机搜索）Windows将展示所有文件夹的目录。

3）选中对应的lastupdated文件，并删除。

4）重新打开（若先前未关闭，请关闭后重新打开）Eclipse,右键报错的项目，并选择Maven > Update Project。同时记得勾选Force Update of Snapshots/Releases”. 点击OK，这样就解决了依赖关系。

**二、Pom.xml文件再次报错**

*\[ERROR\] No goals have been specified for this build. 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. -> \[Help 1\]\[ERROR\] \[ERROR\] To see the full stack trace of the errors, re-run Maven with the -e switch.\[ERROR\] Re-run Maven using the -X switch to enable full debug logging.\[ERROR\] \[ERROR\] For more information about the errors and possible solutions, please read the following articles:\[ERROR\] \[Help 1\][http://cwiki.apache.org/confluence/display/MAVEN/NoGoalSpecifiedException][http_cwiki.apache.org_confluence_display_MAVEN_NoGoalSpecifiedException]*

**解决方法：**

右击报错的项目→Properties→Project Facets→Runtimes→勾选Apache Tomcat v7.0

在Project Facets处找不到Runtimes时，需要点击下图Convert to faceted from…

三、Pox.xml最后报错

*\[ERROR\] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mrpapp: Compilation failure*

*\[ERROR\] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?*

**解决方法：**

在eclipse中找到Window → Preferences → Java → Installed JREs，在jRE home中修改为你安装的jdk的目录位置。

![1240 3][]

好了，3个报错都被处理了，现在我就可以开心的运行项目啦！
