### Question:
MavenScm { public boolean isEmpty() { return this.connection == null && this.developerConnection == null && this.tag == null && this.url == null; } MavenScm(Builder builder); boolean isEmpty(); String getConnection(); String getDeveloperConnection(); String getTag(); String getUrl();  }### Answer:
@Test void isEmptyWithNoData() { MavenScm mavenScm = new MavenScm.Builder().build(); assertThat(mavenScm.isEmpty()).isTrue(); }
@Test void isEmptyWithData() { MavenScm mavenScm = new MavenScm.Builder().connection("some-connection").build(); assertThat(mavenScm.isEmpty()).isFalse(); }
