maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e

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，http://stackoverflow.com/questions/8706017/maven-dependency-plugin-goals-copy-dependencies-unpack-is-not-supported-b

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>
