things you should know about contributing:

1.  API changes require discussion, use cases, etc. Code comes later.
2.  Pull requests are great for small fixes for bugs, documentation, etc.
3.  Pull requests are not merged directly into the master branch.
4.  Code contributions require signing a Google CLA.

API changes

We make changes to Guava's public [APIs][], including adding new APIs, very

        configureProject().assertBuildScriptCompilationAvoided().assertOutputContains("bar")
    }

    @Test
    fun `avoids buildscript recompilation on non ABI change in buildSrc`() {
        val className = givenJavaClassInBuildSrcContains(
            """
            public void foo() {
                System.out.println("foo");
            }
            """
        )

If `values.yaml` is changed, be sure to update corresponding values changes in [../profiles/default.yaml](../profiles/default.yaml)

## Step 3. Update istioctl schema

Istioctl uses a [schema](../../operator/pkg/apis/istio/v1alpha1/values_types.proto) to validate the values. Any changes to
the schema must be added here, otherwise istioctl users will see errors.

import org.junit.Test


class BuildSrcScriptCompileAvoidanceIntegrationTest : AbstractCompileAvoidanceIntegrationTest() {

    @Test
    fun `avoids buildscript recompilation on public function change in buildSrc script`() {
        val packageName = givenKotlinScriptInBuildSrcContains(
            "Foo",
            """
            fun foo() {
                println("foo")
            }
            """
