我做了一些自动化测试，遇到了一个无法编译java.file的问题，我的源文件夹是项目的文件夹“test”。在这个文件夹中，我有2个jar文件：

hamcrest-core-1.3.jar文件

和

junit-4.13.jar

我运行以下命令：

javac -cp junit-4.13.jar;. src\r.java

我得到了下一个信息：

我的代码是来自https://junit.org/junit5/docs/current/user-guide/

import static org.junit.jupiter.api.Assertions.fail;
     import static org.junit.jupiter.api.Assumptions.assumeTrue;

     import org.junit.jupiter.api.AfterAll;
     import org.junit.jupiter.api.AfterEach;
     import org.junit.jupiter.api.BeforeAll;
     import org.junit.jupiter.api.BeforeEach;
     import org.junit.jupiter.api.Disabled;
     import org.junit.jupiter.api.Test;

 class r {

@BeforeAll
static void initAll() {
}

@BeforeEach
void init() {
}

@Test
void succeedingTest() {
}

@Test
void failingTest() {
    fail("a failing test");
}

@Test
@Disabled("for demonstration purposes")
void skippedTest() {
    // not executed
}

@Test
void abortedTest() {
    assumeTrue("abc".contains("Z"));
    fail("test should have been aborted");
}

@AfterEach
void tearDown() {
}

@AfterAll
static void tearDownAll() {
}

 }

我做错了什么？求求你，救命！
