Question

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project sample-java-client-what is the solution

Answer 1

Two things you can do,

1. Delete the old plugin in your pom.xml file.

        <plugin>

            <groupId>org.codehaus.mojo</groupId>

            <artifactId>exec-maven-plugin</artifactId>

            <version>1.2</version>

        </plugin>

2 Also, try running on your machine through command line,

mvn clean install
