Error importing Maven project into Eclipse: No Marketplace Entries found to Handle

Question

I am new to Javaweb programming and when installing the eclipse and importing my project created by Maven, accuses the error below:

No Marketplace Entries found to Handle Maven-antrun-plugin:1.8:run in Eclipse. Please see Help for more information.

What to do to resolve this issue?

This is the pom.xml:

Answer 1

This error happens because the Maven plugin in eclipse (m2eclipse) not having support for goal run in the life Cycle defined, generate-resources. To import, you can do it in two ways:

• disregard the message and import as shown below:

• add the following excerpt to your pom.xml (if you already have any plugin managed, include only the part of plugin, without pluginManagement and plugins):

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
                <lifecycleMappingMetadata>
                    <pluginExecutions>
                        <pluginExecution>
                            <pluginExecutionFilter>
                                <groupId>org.apache.maven.plugins</groupId>
                                <artifactId>maven-antrun-plugin</artifactId>
                                <versionRange>[1.8,)</versionRange>
                                <goals>
                                    <goal>run</goal>
                                </goals>
                            </pluginExecutionFilter>
                            <action>
                                <ignore />
                            </action>
                        </pluginExecution>
                    </pluginExecutions>
                </lifecycleMappingMetadata>
            </configuration>
        </plugin>
    </plugins>
</pluginManagement>

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

This plugin does nothing, has no effect on other Ides or by the command line, just inform the m2eclipse that is to disregard this life cycle, not being presented the error.

What are the consequences of this? Well, like the m2eclipse does not support these life cycles you will not be able to run them using the built-in Eclipse Mven, but it will not interfere with anything in your build itself. In case it has any impact and you need to perform this goal in the eclipse, an alternative is to change the life Cycle to another, as for example prepare-package, being like this:

<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>

EDITION: including pom.xml complete

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