Error. but when I add pluginManagement it stops creating jar for my project.

                    </goals>
                </execution>
            </executions> 
        </plugin>
    </plugins>
     </pluginManagement>
</build>

If I remove pluginManagement from pom then Jar is getting created.

Answer 1

My guess is that you just wrapped your <plugins> tag in a <pluginManagement> tag, which does not do what you want. I suggest you read the documentation to understand the relationship between plugin and pluginManagement. See also another post on StackOverflow.

As to your underlying problem: I guess the error you mention is an Eclipse error. It is emitted by the m2e plugin which requires a connector for each maven plugin in your pom.

You can usually come up with a connector (if it is not found on the Eclipse Marketplace) by typing " m2e connector" into your favorite search engine.

In this case you might want to install this: https://github.com/beskow/openjpa-maven-connector
