无法使用 CLI 编译 java 文件

Question

我进行了一些自动化测试，但遇到了无法编译 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

和

junit-4.13.jar

我运行这个命令：

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

我收到了下一条消息：

src\r.java:1: error: package org.junit.jupiter.api does not exist

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

     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？ 请帮忙！

org.junit.juniper 包表明您的代码使用 JUnit 5。

但是您的类路径中只有 JUnit 4。

遵循JUnit 4 user guide 或更改您的类路径以包含 JUnit 5。
