我有一个 Maven 项目,我想使用 jacoco 进行代码覆盖。这是我的 pom 的相关部分

          <plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<executions>
<execution>
<id>pre-my-test</id>
<phase>pre-integration-test</phase>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<append>true</append>
<destFile>${project.build.directory}/jacoco-it.exec</destFile>
<propertyName>failsafeArgLine</propertyName>
</configuration>
</execution>
<execution>
<id>post-my-test</id>
<phase>post-my-test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<dataFile>${project.build.directory}/jacoco-it.exec</dataFile>
<outputDirectory>${project.reporting.outputDirectory}/jacoco-it</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>

所以我能够很好地运行我的测试,也能够很好地构建项目。然后我就跑了

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

我不断收到类似错误

ERROR] Failed to execute goal org.jacoco:jacoco-maven-plugin:0.7.5.201505241946:
report (post-my-test) on project my-project:
An error has occurred in JaCoCo Test report generation.
Error while creating report:
Error while analyzing class /path/tp/my/project/target/classes/META-INF/
bundled-dependencies/some-third-party-1-jar-with-dependencies.jar@org/slf4j/event/
EventConstants.class. Can't add different class with same name:
org/slf4j/event/EventConstants -> [Help 1]

some-third-party-1-jar-with-dependency.jar 是我拥有的外部依赖项。这是一个 super /阴影 jar 。所以我认为 some-third-party-1-jar-with-dependency.jar 也必须有 org.slf4j,因此发生了冲突。所以我对 pom 进行了更改

            <plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<configuration>
<excludes>
<exclude>**/org/slf4j/event/EventConstants.*</exclude>
</excludes>
</configuration>
<executions>
<execution>
<id>pre-integration-test</id>
<phase>pre-integration-test</phase>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<append>true</append>
<destFile>${project.build.directory}/jacoco-it.exec</destFile>
<propertyName>failsafeArgLine</propertyName>
</configuration>
</execution>
<execution>
<id>post-integration-test</id>
<phase>post-integration-test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<dataFile>${project.build.directory}/jacoco-it.exec</dataFile>
<outputDirectory>${project.reporting.outputDirectory}/jacoco-it</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>

但我仍然遇到同样的错误。我如何确保 jacoco 忽略所有重复的依赖项?我也尝试过

<dependency>
<groupId>some.third.party</groupId>
<artifactId>some-third-party</artifactId>
<version>1</version>
<classifier>jar-with-dependencies</classifier>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
</exclusion>
</exclusions>
</dependency>

但这没有用。是否可以从阴影/ super jar 中排除?

此外,jacoco 为何关心?有什么方法可以修复或忽略这些错误吗?我该如何解决这个问题?

最佳答案

报告目标的

属性排除指定在生成报告期间应从分析中排除哪些文件。如果是 /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependency.jar@org/slf4j/event/EventConstants .class 文件是 /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependency.jar ,剩下的就是关于 JAR 文件中的类。

因此,作为正确配置的示例之一:

<configuration>
<excludes>
<exclude>META-INF/**</exclude>
</excludes>
</configuration>

作为具有pom.xml的证明

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.1</version>
</plugin>
</plugins>
</build>

</project>

src/main/java/Example.java

public class Example {
}

src/test/java/ExampleTest.java

public class ExampleTest {
@org.junit.Test
public void test() {
}
}

执行

mvn clean jacoco:prepare-agent package
mkdir target/classes/META-INF/
cp ~/.m2/repository/org/slf4j/slf4j-api/1.4.2/slf4j-api-1.4.2.jar target/classes
cp ~/.m2/repository/org/slf4j/slf4j-api/1.7.7/slf4j-api-1.7.7.jar target/classes/META-INF
mvn jacoco:report

将失败并显示消息

Error while analyzing /private/tmp/j/target/classes/slf4j-api-1.4.2.jar@org/slf4j/helpers/BasicMarker.class. Can't add different class with same name: org/slf4j/helpers/BasicMarker

同时与包含排除 META-INF/**

pom.xml 执行相同的操作
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.1</version>
<configuration>
<excludes>
<exclude>META-INF/**</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
</build>

</project>

一定会成功。

附注:semantic of property excludes of prepare-agent goal is different - 它指定在执行测试期间应从检测中排除的类名称(无论其在磁盘上的位置如何)。
