execute war file using exec-maven-plugin

Question

I package my spring boot application as a .war file. Then use the

java -jar MyProj-{version}.war

to run it from command prompt.

No I am trying to execute the same command using 'exec-maven-plugin'. But it is failing with the following error

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.6.0:java (default-cli) on project MyProj: The parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin:1.6.0:java are missing or invalid -> [Help 1]

I dint provide the main class as I am not providing in command prompt. Following is my plugin. I use command

exec:java

to run it from eclipse.

Plugin

                </executions>
            </plugin>

Answer 1

Try adding

<executable>java</executable>

into your <configuration> and move <configuration>...</configuration> outside of <executions/> .
