Error importing maven project into Eclipse: In the marketplace entries found to handle

This error occurs because the maven plugin in eclipse ( m2eclipse ) does not support goal run in life cycle set, generate-resources . To import, you can do it in two ways:

• Disregard the message and import, as shown below:

• Addthefollowingexcerpttoyourpom.xml(ifyoualreadyhavesomeplugin),includeonlythepluginpart,withoutpluginManagementandplugins):

Even if you use the first approach you can include the second approach snippet to your pom.xml so that no error is presented to you.

This plugin does nothing, has no effect on other IDEs or the command line, just inform the m2eclipse which is to disregard this lifecycle, not presenting the error.

What are the consequences of this? Well, since m2eclipse does not support these lifecycles you will not be able to run them using the built-in maven of eclipse, but it will not interfere with anything in your build itself. If it does make some impact and you have to run this goal in eclipse, one alternative is to change the life cycle to another, such as prepare-package , thus:

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>gulp</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <target>
                    <echo message="Gulp!" />
                    <exec executable="gulp">
                        <arg value="build" />
                    </exec>
                </target>
            </configuration>
        </execution>
    </executions>
</plugin>

Considering the pom.xml including in the question, it complete and changed would look as follows:
