10/30/2025, 6:33 AMHow does the tooling api work in detail? Does it reuse the Gradle daemon or the host JVM? And what Gradle version will be used? The one specified in the Wrapper?

10/30/2025, 7:19 AMBy default, the TAPI uses / respectes the Gradle version as declared in the wrapper in the project it connects to. However, that Gradle version can be overridden on the connector like e.g. done here.

10/30/2025, 7:19 AMIs there is no Gradle wrapper in the connected project, and none specified on the connector, then I believe a globally installed Gradle version will be used.

I would have expected that the version of the tooling api is used then

10/30/2025, 9:54 AMGlobally installed, are you sure?No, I'm not, hence I write "I believe" 😉 But does the TAPI actually come with a Gradle version? I thought it does not, and thus it could also not be used.

10/30/2025, 10:01 AMIt does not "come with", but it "has a" version.
So if the TAPI is "8.14.3" and neither the build you drive nor the TAPI user specified any version it could behave like if
useGradleVersion("8.14.3")Vampire
10/30/2025, 10:01 AMAlso not sure which is the case, especially as I consider any build without Gradle wrapper files to have a build bug 😄

10/30/2025, 10:07 AMThe TAPI is like the Gradle wrapper you check into the project.
Just a thin layer that provisions the Gradle version if necessary and uses that to drive the build.
Vampire
10/30/2025, 10:07 AMSo it would download the version just like the wrapper would do
Vampire
10/30/2025, 10:08 AMAnd my suspicion was right, I just tried with
Copy code
GradleConnector
.newConnector()
.forProjectDirectory(layout.buildDirectory.dir("bar").get().asFile)
.connect()
.use {
it.newBuild().forTasks("help").setStandardOutput(System.out).run()
}✅ 1
