- * Dokka's integration test task is not cacheable because the HTML outputs
- * it produces when running the tests are used for showcasing resulting documentation,
- * which does not work well with caching.
- *
- * At the moment there are two problems that do not allow to make it cacheable:
- *
- * 1. The task's inputs are such that changes in Dokka's code do not invalidate the cache,
- *    because it is run with the same version of Dokka ("DOKKA_VERSION") on the same
- *    test project inputs.
- * 2. The tests generate HTML output which is then used to showcase documentation.
- *    The outputs are usually copied to a location from which it will be served.
- *    However, if the test is cacheable, it produces no outputs, so no documentation
- *    to showcase. It needs to be broken into two separate tasks: one cacheable for running
- *    the tests and producing HTML output, and another non-cacheable for copying the output.
- *
- * @see [org.jetbrains.dokka.it.TestOutputCopier] for more details on showcasing documentation
