JaCoCo-SonarQube-没有关于每次测试覆盖率的信息

Question

我使用JaCoCo进行代码覆盖。单元测试报告是用junit创建的，它们被正确地导入，因此单元测试信息被正确地显示出来。问题是，我得到了错误消息:没有关于每个测试覆盖率的信息。代码覆盖率显示单元测试、集成测试和整体覆盖率的值为0%。我检查了sonar项目中所有需要的信息，如二进制、src、测试等属性。

我使用的是：＜br＞-SonarQube 4.5.1＜br＞-SonarRunner 2.4＜br＜-MySQL＜br｝-junit 4.1.1＜br＞-jacoco 0.7.2＜br＞

jacoco.exec位于项目基本目录的文件/目标中。

下面你可以看到sonar-project.properties：从我的角度来看，所有必要的路径都设置正确。（即二进制、src、测试）

Comma-separated paths to directories with sources (required)
sonar.sources=src

compiled code
sonar.java.binaries=class

source code of unit tests 
sonar.tests=test/src

Comma-separated paths to files with third-party libraries (JAR files in the case of Java)
sonar.java.libraries=jar

Language
sonar.language=java

Encoding of the source files
sonar.sourceEncoding=UTF-8

Additional parameters
sonar.my.property=value

Set Project Base
sonar.projectBaseDir=C:/snapshots/steffen_latest/software/java

Tells SonarQube to reuse existing reports for unit tests execution and coverage reports
sonar.dynamicAnalysis=reuseReports

JUnit path
sonar.surefire.reportsPath=test/report/junit

Tells SonarQube where the unit tests execution reports are
sonar.junit.reportsPath=test/report/junit

Tells SonarQube that the code coverage tool by unit tests is JaCoCo
sonar.java.coveragePlugin=jacoco

Import JaCoCo code coverage report.
Tells SonarQube where the unit tests code coverage report is
Unit Tests Coverage
sonar.jacoco.reportPath=target/jacoco.exec

Tells SonarQube where the integration tests code coverage report is
sonar.jacoco.itReportPath=target/it-jacoco.exec

这是来自声纳运行器的日志文件：

有人能给我一个建议吗？可能是什么问题？既然我不知道问题出在哪里...几天来我一直在研究这个问题，我真的不知道该怎么办..

提前谢谢你。

在我的情况下，以下命令有效。

mvn clean org.jacoco:jacoco-maven-plugin:0.7.3.201502191951:prepare-agent install
mvn sonar:sonar 

要检查代码覆盖率：启动SonarQube服务器 -

仅供参考：我的SonarQube版本 - 5.1.2。您可以从SonarQube下载下载最新版本

Answer 2

通过这个Maven配置，我可以看到每个测试数据的覆盖率。

您需要配置sonar jacoco侦听器以获得每次测试的覆盖率。

请注意，它已被sonar弃用：“此功能在SonarQube级别已弃用，将不再接受进一步的改进/维护。

    <skipTests>false</skipTests>
            <!--Jacoco settings -->
            <jacoco.haltOnFailure>false</jacoco.haltOnFailure>
            <jacoco.skip>false</jacoco.skip>

            <!-- sonar JACOCO properties -->
            <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
            <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
            <sonar.jacoco.reportPaths>${project.reporting.outputDirectory}/jacoco-ut.exec</sonar.jacoco.reportPaths>

Answer 3

您是否尝试过使用准备代理？

mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install

此外，如果您的承保范围一直显示为0%，您可能需要遵循以下建议：

如果您的项目已经使用argLine来配置surefire-maven-plugin，请确保将argLine定义为属性，而不是插件配置的一部分。"
