Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0

Question

I've got a gradle FAILURE:

..."Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0."

Case description:

• Attached to the project codebase the next libs:

APP/build.gradle

    //(Required) Writing and executing Unit Tests on the JUnit Platform 
testImplementation "org.junit.jupiter:junit-jupiter-api:5.2.0"
testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:5.2.0"
    // (Optional) If you need "Parameterized Tests"
testImplementation "org.junit.jupiter:junit-jupiter-params:5.2.0"
    // (Optional) If you also have JUnit 4-based tests
testImplementation "junit:junit:4.12"
testRuntimeOnly "org.junit.vintage:junit-vintage-engine:5.2.0"

testImplementation "io.mockk:mockk:1.8.5"

• Updated the gradle-wrapper.properties

  distributionUrl=https....gradle-4.4-all.zip to 4.7-all

• after all of that gradle was built success

• created the test calss

  @TestInstance(TestInstance.Lifecycle.PER_CLASS)
    class TestClass {
  
    @Test
    internal fun testName() {
      Assert.assertEquals(2, 1 + 1)
    }
  }
  

• ran the test and got the FAILURE message.

• ran the Gradle build with a command line argument ./gradlew --warning-mode=all to see what exactly the deprecated features are.

As a result I couldn't build the app and I've got that FAILURE: message.

Answer 1

Run the Gradle build with a command line argument --warning-mode=all to see what exactly the deprecated features are.

It will give you a detailed description of found issues with links to the Gradle docs for instructions how to fix your build.

Adding --stacktrace to that, you will also be able to pinpoint where the warning comes from, if it's triggered by outdated code in one of the plugins and not your build script.
