m2e: copy-dependencies is not supported by m2e

Question

I get this error in my pom.xml, and I can't understand what I need to change in order to get eclipse to run the project (run as -> maven build)

        </plugin>
    </plugins>
</build>

The error when trying to build it from within eclipse is

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-site, site, post-site, site-deploy, pre-clean, clean, post-clean. -> [Help 1]

I would really appreciate any help!

Answer 1

From the error message above, it appears that you have tried the Run as -> Maven Build without specifying which maven goal to run.

You should try a specific maven goal - Run as -> Maven install or Run as -> Maven test. Alternately, you can provide a goal in the Maven Build configuration.

Now, as for the warning, copy-dependencies is not supported by m2e, it means that m2e does not support this plugin. Not all the maven functionality are currently supported by m2e.

This worked for me:

To resolve this error all you need to do is copy following code just before your closing tag of build.

       <pluginManagement>
            <plugins>
                <!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->
                <plugin>

                    <artifactId>lifecycle-mapping</artifactId>
                    <version>1.0.0</version>
                    <configuration>

                </plugin>
            </plugins>

I have the same problem as yours

When you want to compile your Maven project using m2eclipse plugin, try

Run as -> Maven Build

then type compile in Goals
