Error “copy-dependencies” in maven

Question

I want copy lib dependencies in maven into lib directory when install project. I used that in my pom file.

<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>

But it's error following:

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

I tried fix it. This is pom file in my project.

<project>

    <version>14.06.201</version>

Please help me!

Answer 1

I solved this bug. The repository that I'm using is not available therefore Maven can not download the plugins.

Answer 2

For me it looks like it's trying to find version 1.0 of maven-dependency-plugin which isn't available in Maven Central. Use 2.4 version as you did in first POM snippet you had pasted and it should be OK.
