我希望在安装项目时将maven中的lib lib依赖项放入lib目录中。 我在我的pom文件中使用了它。
<project>
<dependencies>
...
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>

</goals>
<configuration>
<outputDirectory>${project.build.directory}/dependencies</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
但是下面是错误：
Description Resource Path Location Type
maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e. pom.xml /jasperreports-test line 60 Maven Project Build Lifecycle Mapping Problem
我试过修理它。 这是我项目中的pom文件。

请帮助我！
答案 0 :(得分：2)
对我而言，它似乎正在尝试查找1.0 maven-dependency-plugin 2.4的版本{{1}}。使用{{1}}版本，就像在粘贴的第一个POM代码段中一样，它应该没问题。

我解决了这个错误。我正在使用的存储库不可用，因此Maven无法下载插件。
