Error when trying to change wrapper version on wrapper task

Help/Discuss Plugin Portal

Inside build.gradle I am trying to do something like this

task wrapper(type: Wrapper){
if(BUILD_API.toInteger() >= 30 && BUILD_USE_11.toBoolean()) // Basically as is mentioned is Build >= 30 and want to use Java 11+
{
gradleVersion = ‘7.5’
distributionType = Wrapper.DistributionType.ALL
// distributionUrl=‘https\://services.gradle.org/distributions/gradle-7.5-all.zip’
}
else
{
gradleVersion = ‘6.7.1’
distributionType = Wrapper.DistributionType.ALL
// distributionUrl=‘https\://services.gradle.org/distributions/gradle-6.7.1-all.zip’
}

}

I want to keep some old devs running, but I get this error.

Cannot add task ‘wrapper’ as a task with that name already exists.

then using your literature

https://docs.gradle.org/7.3/userguide/gradle_wrapper.html

Tried as:

tasks.named(‘wrapper’) {
if(BUILD_API.toInteger() >= 30 && BUILD_USE_11.toBoolean())
{
gradleVersion = ‘7.5’
distributionType = Wrapper.DistributionType.ALL
// distributionUrl=‘https\://services.gradle.org/distributions/gradle-7.5-all.zip’
}
else
{
gradleVersion = ‘6.7.1’
distributionType = Wrapper.DistributionType.ALL
// distributionUrl=‘https\://services.gradle.org/distributions/gradle-6.7.1-all.zip’
}
}

and i get this error

problem occurred evaluating project ‘:app’.

Failed to apply plugin ‘com.android.internal.application’.
Failed to create service ‘com.android.build.gradle.options.ProjectOptionService_380a0b53-dfb7-4b5e-9298-105695e17a43’.
Could not create an instance of type com.android.build.gradle.options.ProjectOptionService.
Cannot obtain value from provider of Gradle property ‘android.testInstrumentationRunnerArguments.package’ at configuration time.
Use a provider returned by ‘forUseAtConfigurationTime()’ instead.

I guess because is not getting the proper android tools

Even though in both cases in build.gradle inside dependencies for android.

(NOTE same error testing by commenting version/type and using final distributionUrl)

buildscript {

repositories {
    google()
    mavenCentral()
    maven { url "https://maven.google.com" }
    //AllBuildRepos
}
dependencies {
    if(BUILD_API.toInteger() >= 30 && BUILD_USE_11.toBoolean())
    {
        classpath 'com.android.tools.build:gradle:7.4.0'
    }
    else
    {
        classpath 'com.android.tools.build:gradle:4.2.0'
    }


}

}

note if I do the change manually in gradle-wrapper.properties, everything work as expected

and the final reason in build.gradle.app

compileOptions {
    if(BUILD_API.toInteger() >= 30 && BUILD_USE_11.toBoolean())
    {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }
    else
    {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Is this possible?, what I missed here

Thanks in advance

The wrapper task is only present on the root project of a build.
So you shouldn’t try to configure it on a subproject as it then is not found as you have seen.

Btw. you shouldn’t use the -all distribution.
It has exactly one use-case where it is helpful.

When using Groovy DSL build scripts
and only while actually editing them.

For all other use-cases, you just waste the time, bandwidth and diskspace of everyone and anything just executing the build.
And if you would switch to Kotlin DSL, you wouldn’t have any reason anymore at all, while having amazingly better IDE support, if you use a proper IDE like IntelliJ. :wink:

Thanks for your suggestion and clarification :smiley:

I will dig more on this Kotlin DSL.
