From mobile apps to microservices, from small startups to big enterprises, Gradle helps teams build, automate and deliver better software, faster.

Gradle Community

If the included builds are via `include("some-other-module")` then only the root gradle.properties is used.

It's more like `includeBuild("some-other-project")`

ah yea.  unsure on how composite builds process gradle.properties.

for all our projects there’s a core convention plugin that, among other things, standardizes certain settings in gradle.properties.

Can this be even done in a plugin ? :thinking_face:

Like `jvmArgs`  needs to be read before the dameon starts

it can be done in a plugin, but changes only take effect on the next run.

Super curious how that works. Do you have any documentation on this?

nothing fancy.  simple custom task that takes a gradle.properties template as input, has gradle.properties as output, will only run if the template has changed.  really no different than manually editing it, but baked into the builds so things stay consistent at scale.

sorry to disappoint.  i’m often hoping to learn of some super-secret-awesome-api that saves the day :wink:

```@CacheableTask
internal abstract class WriteGradleProperties : DefaultTask() {
    @get:OutputFile
    abstract val gradlePropertiesFile: RegularFileProperty

    @get:Input
    abstract val defaultProperties: MapProperty&lt;String, String&gt;

    @TaskAction
    fun taskAction() {
// merge logic here
}
}```

As far as I know composite builds don't get gradle.properties passed along: <https://github.com/gradle/gradle/issues/2534>

The build cache configuration is for the whole build and will be passed down to included builds. Whether the build cache is on or off is also a build wide setting and can’t be changed on a per included build level.

Here is some documentation on that behaviour: <https://docs.gradle.org/current/userguide/build_cache.html#sec:build_cache_composite>

Thanks! Looks like "it depends" then? For a given Gradle property, can I know if it's going to be passed down or not, besides trying it?

I am pretty sure all the Gradle properties will be used from the root build and affect all included builds as well: <https://docs.gradle.org/release-candidate/userguide/build_environment.html#sec:gradle_configuration_properties>
