hey everyone so i was trying to add a java(ant) proj to a kotlin(gradle) proj as a subproj so that i could import it in some Kotlin class? The current file structure is something like this:

.
├── build.gradle.kts
├── src
├── settings.gradle.kts
└── JavaProj(ant)
    ├── ant.settings
    └── build.xml

i hope i could make this file stucture clear. but the issue is i could not import the java proj in the kotlin. I think its something realted to including the proj in settings.gradle.kts but searching stackoverflow wasnt enough. Is there something else i ned to do as well while importing another subproj?

I don't think gradle will know how to import an ant project out of the box… there might be a gradle plugin that can do it?

Edit - I may be wrong, explore https://docs.gradle.org/current/userguide/ant.html

[Rob Elliot]

May be easier to build the ant project and include the resulting jar as a file system dependency in gradle.

I does know how to do it out of the box. Ant is a first class citizen in Gradle

Imho the best way would be to replace the Ant build by a Gradle build, but importing the Ant build should work just fine.

[Ansh Tyagi]

adding the build in build.gradle.kts using ant.importBuild throws an error that

Cannot add task 'build' as a task with that name already exists.

i tried registering another task usig tasks.register. But i am still not able to import the classes from JavaProject to some Kotlinclass in kotlin project

[Ansh Tyagi]

oh alright i found Transformer function to actually rename it

[Ansh Tyagi]

but still cannot import it using the import keyword in the kt file

[Ansh Tyagi]

Lets say that there is a Runner.run() metho in the java project that i need to exec in the Kotlin class

[Vampire]

No, don't import the build in the existing project

[Vampire]

You include the project in the settings script, you add an own cradle script for that project and there you import it. Then you also don't have a naming clash

[Ansh Tyagi]

i did include that javaproj in the in the settings script. and then tried ant.importBuild. Are you saying that i should change the ant build to the gradle build and then try to import that method?

[Vampire]

In JavaProj/build.gradle.kts
