     * This is a workaround to preserve backward compatibility with IntelliJ IDEA.
     * The problem only occurs in IntelliJ IDEA because it parses {@link OperationDescriptor#getDisplayName()} to get the test display name.
     * Once its code is updated to use {@link org.gradle.tooling.events.test.TestOperationDescriptor#getTestDisplayName()}, the workaround can be removed as well.
     * Alternatively, it can be removed in Gradle 9.0.

Tasks either come from *build scripts* or *plugins*.

Once we apply a plugin to our project, such as the `application` plugin, additional tasks become available:

.build.gradle.kts
