内容图文
我想在安装项目时将maven中的lib依赖项复制到lib目录中.
我在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>
<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>
但这是以下错误：
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
我尝试修复它.
这是我项目中的pom文件.
<project>
<groupId>com.vccorp.adtech</groupId>
<artifactId>UserAgentService</artifactId>
<version>14.06.201</version>
<name>UserAgentService</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
</dependency>
</dependencies>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>

<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>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<id>copy</id>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>
${project.build.directory}/lib
</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
但是在安装时会出现以下错误：

请帮我！
解决方法:
对我来说,它似乎正在尝试找到版本isn’t available in Maven Central的maven-dependency-plugin 1.0.就像在粘贴的第一个POM代码段中那样使用2.4版本,应该可以.
