• 类名与注解名冲突，必须使用全限定名区分

publicclassTest{@org.junit.jupiter.api.Testpublicvoidtest1_1(){}}

• 如果强制使用导入语句，则下述代码报错

1. public class Test {处报错：'Test' is already defined in this compilation unit

2. @Test处报错：Annotation type expected

importorg.junit.jupiter.api.Test;publicclassTest{@Testpublicvoidtest1_1(){}}
