Jacoco在运行gradle任务时显示coverage 0.0，但从Intellij运行时显示正确

Question

我正在使用Jacoco插件来计算Spring Boot应用程序的代码覆盖率。 build.gradle中的Jacoco配置如下所示：

jacocoTestReport {
reports {
    xml.enabled false
    csv.enabled false
    html.destination file("${buildDir}/jacocoHtml")
}

afterEvaluate {
    classDirectories = files(classDirectories.files.collect {
        fileTree(dir: it,
                exclude: ['**/models/**',
                          '**/config/**',
                          '**/constants/**',
                          '**/Application.class'])
    })
}

}

和

jacocoTestCoverageVerification {
violationRules {
    rule {
        element = 'PACKAGE'
        excludes = ['some packages']
        limit {
            counter = 'BRANCH'
            minimum = 0.7
        }
    }
}

}

当我从IntelliJ运行coverage时，它显示正确的结果，但是当我使用gradlew clean buils运行时，它的覆盖范围为0.0。

我已经编写了一个示例类，这是jacoco报告快照- 报告： 类别： 我为SomeClass编写的测试是

public class SomeClassTest {
private SomeClass someClass;

@Before
public void setUp() throws Exception {
    someClass = new SomeClass(12, 23);
}

@Test
public void shouldSumTwoValues() {
    assertThat(someClass.sum()).isEqualTo(35);
}

}

有人可以帮我吗？

src/main/java/SomeClass.java

class SomeClass { private Integer value1; private Integer value2; SomeClass(Integer value1, Integer value2) { this.value1 = value1; this.value2 = value2; } Integer sum() { return value1 + value2; } }

src/test/java/SomeClassTest.java

和import org.junit.*; import static org.junit.Assert.*; public class SomeClassTest { private SomeClass someClass; @Before public void setUp() throws Exception { someClass = new SomeClass(12, 23); } @Test public void shouldSumTwoValues() { assertEquals(35, (int) someClass.sum()); } }

build.gradle

执行apply plugin: "java" apply plugin: "jacoco" dependencies { testCompile "junit:junit:4.12" } repositories { mavenCentral() } 在gradle test jacocoTestReport中产生以下报告

除build/reports/jacoco/test/html/index.html外的

build.gradle

除了更改带有jacocoTestReport { reports { xml.enabled false csv.enabled false html.destination file("${buildDir}/jacocoHtml") } afterEvaluate { classDirectories = files(classDirectories.files.collect { fileTree(dir: it, exclude: ['**/models/**', '**/config/**', '**/constants/**', '**/Application.class']) }) } } jacocoTestCoverageVerification { violationRules { rule { element = 'PACKAGE' excludes = ['some packages'] limit { counter = 'BRANCH' minimum = 0.7 } } } } 上的报告的目录之外，不会更改结果/报告。

Answer 2

就我而言，我发现这是因为我设置了最小值 = 1。当我突然将其更改为 0.9 时，它起作用了
