问题描述

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>报告< / 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并且还可以很好地构建项目。然后我运行

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

我一直收到错误，如

 错误]无法执行目标org.jacoco：jacoco-maven-plugin：0.7.5.201505241946：项目my-project上的
报告（post-my-test）：
 JaCoCo Test中发生错误报告生成。 
创建报告时出错：
分析类时的错误/ path / tp / my / project / target / classes / META-INF / 
 bundled-dependencies / some-third-party-1- jar-with-dependencies.jar@org/slf4j/event/ 
 EventConstants.class。无法添加具有相同名称的不同类：
 org / slf4j / event / EventConstants  - > [帮助1]

some-third-party-1-jar-with -dependencies.jar 是我拥有的外部依赖项。这是一个超级/阴影的罐子。所以我认为某些第三方-1-jar-with-dependencies.jar 也必须有 org.slf4j ，因此冲突。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>

< outputDirectory> $ {project.reporting.outputDirectory} / jacoco-it< / outputDirectory> 
< / configuration> 
< / execution> 
< / executions> 
< / plugin>

但我仍然得到同样的错误。如何确保jacoco忽略所有重复的依赖项？我也试过了

 < dependency> 
< groupId> some.third.party< / groupId> 
< artifactId>某些第三方< / 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>

但这不起作用。是否可以从阴影/超级罐中排除？



此外，为什么jacoco会关心？有没有办法修复或忽略这些错误？如何解决此问题？

解决方案

物业不包括<$ code> report 目标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-dependencies.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-dependencies.jar ，其余的是关于JAR文件中的类。



因此作为正确配置的示例之一：

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

作为证明 pom.xml 

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

< / project>

src / main / java / Example.java 

 公共类示例{
}

和 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：报告

将失败并显示消息

 分析/private/tmp/j/target/classes/slf4j-api-1.4.2.jar@org/slf4j/helpers/BasicMarker.class时出错。无法添加具有相同名称的不同类：org / slf4j / helpers / BasicMarker

同时执行 pom.xml 包含 $ META-INF / ** 

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

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

将成功。



作为一方注意：财产的语义不包括 prepare-agent 目标不同 - 它指定在执行测试期间应从检测中排除的类名（无论其磁盘位置如何）。 / p>

I have a maven project and I want to use jacoco for code coverage. Here is the relevant section of my pom

          <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>

                        <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>

So I am able to run my tests just fine and also build the project just fine. Then I run

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

I keep getting errors like

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:

EventConstants.class. Can't add different class with same name: 
org/slf4j/event/EventConstants -> [Help 1]

some-third-party-1-jar-with-dependencies.jar is an external dependency that I have. This is an uber/shaded jar. So I thought that some-third-party-1-jar-with-dependencies.jar must also have org.slf4j, hence the conflict. So I made a change to the pom as

            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>

                    </excludes>

                <executions>

                        <phase>pre-integration-test</phase>
                        <goals>
                            <goal>prepare-agent</goal>
                        </goals>

                        </goals>
                        <configuration>
                            <dataFile>${project.build.directory}/jacoco-it.exec</dataFile>
                            <outputDirectory>${project.reporting.outputDirectory}/jacoco-it</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

but I still get the same error. How can I make sure that jacoco ignores all duplicate dependencies? I also tried

<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>

but that did not work. Is it possible to have exclusions from shaded/uber jars?

Moreover, why does jacoco care? Is there any way to fix or ignore these errors? How can I resolve this issue?

解决方案

Property excludes of report goal specifies which files should be excluded from analysis during generation of report. In case of /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependencies.jar@org/slf4j/event/EventConstants.class file is /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependencies.jar , and the rest is about class in JAR file.

Therefore as one of examples of correct configuration:

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

As a proof having pom.xml

<?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">

public class Example {

and src/test/java/ExampleTest.java

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

Execution of

mvn clean jacoco:prepare-agent package

cp ~/.m2/repository/org/slf4j/slf4j-api/1.7.7/slf4j-api-1.7.7.jar target/classes/META-INF
mvn jacoco:report

will fail with message

while same execution with pom.xml containing exclusion of META-INF/**

    </plugins>
  </build>

</project>

will succeed.

As a side note: semantic of property excludes of prepare-agent goal is different - it specifies class names (regardless of their on-disk location) that should be excluded from instrumentation during execution of tests.
