From logs it does look like its referring to wrong mvn path when using eclipse

Can you execute build from command like and see if there is any issue?

Hi,

It seems you have older version of maven and your projects parent POM enforce to use plugin within range.

Either you can install latest version of Maven or change the range from parent POM file.

You can find below plugin in your POM.

<!-- Maven Enforcer Plugin -->

  <plugin>

  <groupId>org.apache.maven.plugins</groupId>

  <artifactId>maven-enforcer-plugin</artifactId>

  <executions>

  <execution>

  <id>enforce-maven</id>

  <goals>

  <goal>enforce</goal>

  </goals>

  <configuration>

  <rules>

  <requireMavenVersion>

  <version>[3.3.9,)</version>

  </requireMavenVersion>

  <requireJavaVersion>

  <message>Project must be compiled with Java 8 or higher</message>

  <version>1.8.0</version>

  </requireJavaVersion>

  </rules>

  </configuration>

  </execution>

  </executions>

  </plugin>

Hi Arun,

Thanks a lot for your help.

To fix the issue , I did the below 2 steps.

I have reinstalled the m2eclipse plugin in my eclipse.

I have changed maven-enforcer-plugin to [3.0.0,)

<artifactId>maven-enforcer-plugin</artifactId>

                <executions>

                    <execution>

                        <id>enforce-maven</id>

                        <goals>

                            <goal>enforce</goal>

                        </goals>

                        <configuration>

                            <rules>

                                <requireMavenVersion>

                                    <version>[3.0.0,)</version>

                                </requireMavenVersion>

Anybody knows which maven version supports maven-enforcer-plugin as 3.3.9

[arunpatidar]

for me its working with Apache Maven 3.5.2
