Could not set unknown property 'outputDir' for Main Solidity Sources of type org.gradle.api.internal.file.DefaultSourceDirectorySet.

I'm getting

> Failed to apply plugin class 'org.web3j.solidity.gradle.plugin.SolidityPlugin'.
   > Could not set unknown property 'outputDir' for Main Solidity Sources of type org.gradle.api.internal.file.DefaultSourceDirectorySet.

The code:

buildscript {
    repositories {
        maven("https://artifacts.consensys.net/public/maven/maven/")
    }
}

plugins {
    kotlin("jvm") version "1.9.23"
    id("org.web3j") version "4.11.2"
}

Tested Gradle versions: 8.4, 8.7

Workaround competitive plugin id("io.github.ehdrbs0318.lazy3j") version "1.0.4" seems to work

Same here:

An exception occurred applying plugin request [id: 'org.web3j', version: '4.11.3']

gradle 8.7, java 17

Looks to be an issue when using a gradle version >= 8.0

Quote from https://docs.gradle.org/7.6/javadoc/org/gradle/api/file/SourceDirectorySet.html#setOutputDir:

setOutputDir @Deprecated void setOutputDir​(Provider<java.io.File> provider) Deprecated. Use getDestinationDirectory().set() instead. This method will be removed in Gradle 8.0. Sets the provider that gives the directory to assemble the compiled classes into. Parameters: provider - provides output directory for this source directory set Since: 4.0

Yes it is due to incompatibility with gradle version >=8.5. We are working on updating all web3j repos to gradle 8.5
