使用compileOnly和testCompileOnly时,gradle测试失败

我有一个小的gradle库项目,它只有两个文件和两个测试:

RandomUtils.java

final class RandomUtils {

    private static final SecureRandom random = new SecureRandom();

    private RandomUtils() {
    }

    static String nextRandomId() {
        return new BigInteger(130, random).toString(32);
    }

}

URLUtils.java

public class URLUtils {

    private URLUtils() {
    }

    /**
     * Return the base url (eg: http://localhost:8080)
     * @param request
     * @return String
     * @throws MalformedURLException
     */
    public static String getURLBase(HttpServletRequest request) throws MalformedURLException {
        URL requestURL = new URL(request.getRequestURL().toString());
        String port = requestURL.getPort() == -1 ? "" : ":" + requestURL.getPort();
        return requestURL.getProtocol() + "://" + requestURL.getHost() + port;
    }

}

这些是相关的测试:

@RunWith(JUnit4.class)
public class RandomUtilsTest {

    @Test
    public void testConstructorIsPrivate() throws Exception {
        Constructor constructor = RandomUtils.class.getDeclaredConstructor();
        assertTrue(Modifier.isPrivate(constructor.getModifiers()));
        constructor.setAccessible(true);
        constructor.newInstance();
    }

    @Test
    public void nextRandomId() throws MalformedURLException {
        assertNotNull(RandomUtils.nextRandomId());
    }

}

@RunWith(JUnit4.class)
public class URLUtilsTest {

    @Test
    public void testConstructorIsPrivate() throws Exception {
        Constructor constructor = URLUtils.class.getDeclaredConstructor();
        assertTrue(Modifier.isPrivate(constructor.getModifiers()));
        constructor.setAccessible(true);
        constructor.newInstance();
    }
    @Test
    public void getURLBase() throws MalformedURLException {
        MockHttpServletRequest request = new MockHttpServletRequest();
        request.setRequestURI("/entity");
        assertEquals("http://localhost", URLUtils.getURLBase((HttpServletRequest) request));
        request.setRequestURI(":8080/entity");
        assertEquals("http://localhost:8080", URLUtils.getURLBase((HttpServletRequest) request));
    }

}

我有以下build.gradle

dependencies {
    compileOnly("javax.servlet:javax.servlet-api:${javaxServletApiVersion}")
    testCompileOnly("javax.servlet:javax.servlet-api:${javaxServletApiVersion}")
    testCompileOnly("org.springframework:spring-test:${springVersion}")
    testCompileOnly("junit:junit:${junitVersion}")
}

我没有在intellij中遇到依赖关系的任何问题,但是当我尝试运行./gradlew clean build时,我在运行任务:common:webutils:test时出现此错误:

java.lang.NoClassDefFoundError: org/springframework/mock/web/MockHttpServletRequest
    at com.domain.api.common.webutils.URLUtilsTest.getURLBase(URLUtilsTest.java:27)

我查看了gradle documentation,并说明了

  • compileOnly :仅编译时间依赖项,而不是在运行时使用
  • testCompileOnly :仅用于编译测试的附加依赖项,未在运行时使用

我的配置是否正确?如果测试和src都存在javax.servlet:javax.servlet-api:${javaxServletApiVersion},为什么它在测试期间失败?

你已经回答了自己的问题:

  

testCompileOnly :仅用于编译测试的附加依赖项,未在运行时使用

testCompileOnly在编译测试时可用,而不是在执行时。如果您仅在测试执行时需要某些内容,而不是像slf4j绑定或类似内容那样进行编译,则属于testRuntime。如果您需要编译测试以及运行时,那么它属于testCompile
