Configure gradle.build to build all spring boot sub projects to jars

Question

I have multi-module Gradle project. Each module is full application with own @SpringBootApplication. Root project has no sources in src. How to configure root/build.gradle to build all sub-modules to executable JARs on executing ./gradlew build command from root directory?

Answer 1

You could create a custom task in your root module that will execute build task for all submodules :

task buildAll() {
    subprojects.forEach {
        buildAll.dependsOn it.tasks.getByName('build')
    }
}

and then invoke it :

./gradlew buildAll

This way every submodule will be build and boot jar will be available in the build/libs directory of every submodule. Also you can name this task build - it all depends on your current configuration.
