How to Pass Command Line Arguments for Gradlew?

You can pass command line arguments to gradlew (the Gradle wrapper) in the same way you would pass arguments to any other command line tool. Here's how:

Passing Arguments to Gradle Tasks

1. Directly after the task name: You can append arguments to the task name, separated by spaces.

   ./gradlew build -x test -Dmy.custom.property=value

   • build: The Gradle task to execute.
   • -x test: Excludes the test task from execution.
   • -Dmy.custom.property=value: Sets a system property named my.custom.property to the value value.

2. Using --args: You can pass arguments to the task using the --args flag.

   ./gradlew build --args "-x test -Dmy.custom.property=value"

   • build: The Gradle task to execute.
   • --args "-x test -Dmy.custom.property=value": Passes arguments to the build task.

Passing Arguments to the Gradle Wrapper

1. Using -P: You can set Gradle properties using the -P flag.

   ./gradlew -Pmy.custom.property=value build

   • -Pmy.custom.property=value: Sets the Gradle property my.custom.property to the value value.
   • build: The Gradle task to execute.

Accessing Arguments in Gradle Scripts

You can access command line arguments in your Gradle build scripts using the project.properties map.

task myTask {
  doLast {
    println "Custom property value: ${project.properties['my.custom.property']}"
  }
}

Practical Insights

• Use -x to exclude tasks from execution.
• Use -D to set system properties, which are available to all tasks.
• Use -P to set Gradle properties, which are specific to the current build.
• Access arguments in your Gradle scripts using the project.properties map.
