最近在开发Cloudstack部分功能时遇到了如下问题：maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e
解决的办法很简单，，让eclipse忽略（Ignore）这个error即可
另外网上也有直接修改pom文件的方式解决的，
修改前：
have a fairly simple Maven project:
<project><dependencies>…</dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-dependency-plugin</artifactId><version>2.4</version><executions><execution><id>copy-dependencies</id><phase>package</phase><goals><goal>copy-dependencies</goal></goals><configuration><outputDirectory>${project.build.directory}/dependencies</outputDirectory></configuration></execution></executions></plugin></plugins></build></project>
修改后：
It seems to be a known issue. You should instruct m2e to ignore this. Add the following inside your<build/> tag:
<pluginManagement><plugins><!– Ignore/Execute plugin execution –><plugin><groupId>org.eclipse.m2e</groupId><artifactId>lifecycle-mapping</artifactId><version>1.0.0</version><configuration><lifecycleMappingMetadata><pluginExecutions><!– copy-dependency plugin –><pluginExecution><pluginExecutionFilter><groupId>org.apache.maven.plugins</groupId><artifactId>maven-dependency-plugin</artifactId><versionRange>[1.0.0,)</versionRange><goals><goal>copy-dependencies</goal></goals></pluginExecutionFilter><action><ignore /></action></pluginExecution></pluginExecutions></lifecycleMappingMetadata></configuration></plugin></plugins></pluginManagement>
你说只有有缘人才可以取下，我看着你手中的戒指，
