Why the gradle war task is skipped? : <p>I am a new convert to gradle. Most of the tasks work fine. However I see that the war task is always skipped. When I run in the debug mode, I see the following logs -</p>

<blockquote>
  <p>09:12:34.889 [LIFECYCLE] [class
  org.gradle.internal.buildevents.TaskExecutionLogger] :war 09:12:34.889
  [DEBUG]
  [org.gradle.api.internal.tasks.execution.ExecuteAtMostOnceTaskExecuter]
  Starting to execute task ':war' 09:12:34.889 [INFO]
  <strong>[org.gradle.api.internal.tasks.execution.SkipOnlyIfTaskExecuter] Skipping task ':war' as task onlyIf is false.</strong> 09:12:34.889 [DEBUG]
  [org.gradle.api.internal.tasks.execution.ExecuteAtMostOnceTaskExecuter]
  Finished executing task ':war' 09:12:34.889 [LIFECYCLE] [class
  org.gradle.internal.buildevents.TaskExecutionLogger] :war SKIPPED</p>
</blockquote>

<p>I am not sure why onlyIf is false. I did search on internet. But I did not find anything related.</p>

<p>Here is my gradle file -</p>

    }

        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }

<p>If you could help me with generating the war file that would be great.</p>
