Here's a more complete example.

Use a dependency to check if the username and password are correct.

For this, use the Python standard module <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> to check the username and password.

                InputStream jdksExtendIS =
                        MavenToolchainMergerTest.class.getResourceAsStream("toolchains-jdks-extend.xml")) {
            PersistedToolchains jdks = read(jdksIS);
            PersistedToolchains jdksExtend = read(jdksExtendIS);
            assertEquals(2, jdks.getToolchains().size());
