我试图使用Maven (m2eclipse)建立一个项目,但我在Eclipse中得到这个错误:

Description Resource Path Location Type Could not calculate build plan: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from http://repo1.maven.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.plugins:maven-compiler-plugin:pom:2.0.2 from/to central (http://repo1.maven.org/maven2): No response received after 60000 ExampleProject Unknown Maven Problem

什么好主意吗? 如果你能告诉我如何检查是否一切配置正常,那就太有帮助了。


当前回答

我在Eclipse 3.6和m2eclipse中有类似的问题。

无法计算构建计划:未能将org.apache.maven.plugins:maven-resources-plugin:jar:2.4.3从http://repo1.maven.org/maven2传输到本地存储库中,直到central的更新间隔已过或强制更新,才会重新尝试解决方案。原始错误:无法从中心转移工件org.apache.maven.plugins: Maven -resources-plugin:jar:2.4.3 (http://repo1.maven.org/maven2): ConnectException project1未知Maven问题

删除所有maven*。来自本地存储库的lastUpdated文件(正如Deepak Joy建议的那样)解决了这个问题。

这件事也发生在我身上,对此你可能有两种解决办法

If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C:\Users\Mohit.Singh.m2\repository folder and then you have to run mvn eclipse:eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --> GO to maven --> Click on update project a window will appear check the force snapshot download option and hit on OK

尝试执行

mvn -U clean

或者在eclipse中运行> Maven Clean和Maven >更新项目上下文菜单中的快照

您可以删除.m2文件夹本身,并强制MyEclipse在启动时重新下载所有依赖项。进入Window > Preferences > MyEclipse > Maven4MyEclipse。

如果你是一个代理,你必须更新settings.xml文件(在你的MAVEN_HOME的conf文件夹下,文件本身包含关于代理设置的信息),另外你可能需要更新你的Eclipse网络设置(窗口->Preferences…)—>类型Network Connections)。

尝试使用-X或——debug来获得调试输出,这可以提供关于问题的额外信息。

请确保。m2文件夹中的settings.XML文件是有效的 然后在cmd中使用以下命令清理存储库

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i
