### Verifying signatures

Once you've downloaded a Gradle JAR file or a distribution and its corresponding signature file (with a `.asc` extension), you can verify its authenticity against the public key.

For example, to verify the signature of `plugin-publish-plugin-2.0.0.jar` and its signature file `plugin-publish-plugin-2.0.0.jar.asc`, use this command:

```bash

  // For now, we'll keep the standard ones and allow modules to add more
  androidSignature(library("signature-android-apilevel21")) { artifact { type = "signature" } }
  jvmSignature(library("codehaus-signature-java18")) { artifact { type = "signature" } }

  "lintChecks"(library("androidx-lint-gradle"))
}

configure<com.android.build.api.dsl.Lint> {
  xmlReport = true
  checkDependencies = true
}

def _get_signature(call: Callable[..., Any]) -> inspect.Signature:
    try:
        signature = inspect.signature(call, eval_str=True)
    except NameError:
        # Handle type annotations with if TYPE_CHECKING, not used by FastAPI
        # e.g. dependency return types
        if sys.version_info >= (3, 14):
            from annotationlib import Format

            signature = inspect.signature(call, annotation_format=Format.FORWARDREF)

        // For now, we test that the method signature is correct and can be called

        AtomicInteger callbackCount = new AtomicInteger(0);

        try {
            // This will likely fail due to missing SearchEngineClient setup,
            // but we can verify the method signature and basic functionality
            SearchEngineUtil.scroll("test_index", hit -> {

            // Try to call the expired method
            // Note: This method may fail in test environments due to system dependencies
            // but we mainly want to ensure the method signature is correct
            testTarget.expired();

            // If we get here, the method executed successfully
            assertTrue("expired method executed successfully", true);
        } catch (Throwable t) {

  static double getMinValue(double[] array, int from) {
    // This is basically a copy of com.google.math.Rank#getMinValue, with a small change in the
    // method signature: we always search to the end of the array.
    int min = from;
    for (int i = from + 1; i < array.length; i++) {
      if (array[min] > array[i]) {
        min = i;
      }
    }
    return array[min];

        // Test parameter accepts final boolean (compile-time verification)
        authenticator.setUseV2Endpoint(true);
        authenticator.setUseV2Endpoint(false);

        // Verify method signature is correct
        assertTrue(true);
    }

    @Test
    public void test_defaultMaxGroupDepth() {
        EntraIdAuthenticator authenticator = new EntraIdAuthenticator();

  static double getMinValue(double[] array, int from) {
    // This is basically a copy of com.google.math.Rank#getMinValue, with a small change in the
    // method signature: we always search to the end of the array.
    int min = from;
    for (int i = from + 1; i < array.length; i++) {
      if (array[min] > array[i]) {
        min = i;
      }
    }
    return array[min];
