Jacoco 如何正确排除包

Question

我正在使用 Jacoco Maven 插件版本 0.8.1（使用 Java 8 / Maven 3.1.0）。 无法让 Jacoco 使用路径排除。 我想排除这些软件包：

• my.package.model

• my.package.exception

我尝试过的：

<build>
      <plugins>
            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.8.1</version>
                <executions>
                    <execution>
                        <id>prepare-agent</id>
                        <goals>
                            <goal>prepare-agent</goal>
                        </goals>  
                    </execution>
                </executions>
                <configuration>
                    <excludes>
                        <exclude>my.package.model</exclude>
                        <exclude>my.package.exception</exclude>
                    </excludes>
                </configuration>
            </plugin>
      </plugins>
</build>

<reporting>
        <plugins>
             <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.8.1</version>
                <configuration>
                    <excludes>
                        <exclude>my.package.model</exclude>
                        <exclude>my.package.exception</exclude>
                    </excludes>
                </configuration>
                <reportSets>
                    <reportSet>
                        <reports>
                            <report>report</report>
                        </reports>
                    </reportSet>
                </reportSets>
            </plugin>
        </plugins>
</reporting>

还有（对于

excludes

部分）：

<excludes>
     <exclude>my.package.model**</exclude>
     <exclude>my.package.exception**</exclude>
</excludes>

<excludes>
     <exclude>my/package/model/**/*</exclude>
     <exclude>my/package/exception/**/*</exclude>
</excludes>

<excludes>
     <exclude>*/my/package/model/**/*</exclude>
     <exclude>*/my/package/exception/**/*</exclude>
</excludes>

<excludes>
     <exclude>**/my/package/model/**/*</exclude>
     <exclude>**/my/package/exception/**/*</exclude>
</excludes>

<excludes>
     <exclude>**/my/package/model/**</exclude>
     <exclude>**/my/package/exception/**</exclude>
</excludes>

<excludes>
     <exclude>**/my/package/model/*</exclude>
     <exclude>**/my/package/exception/*</exclude>
</excludes>

<excludes>
     <exclude>**/model/*</exclude>
     <exclude>**/exception/*</exclude>
</excludes>

<excludes>
     <exclude>**/model**</exclude>
     <exclude>**/exception**</exclude>
</excludes>

无法从最终报告中删除这些软件包......令人沮丧。

我读到：

• 使用 Gradle 过滤 JaCoCo 覆盖率报告
• Jacoco 排除类
• Jacoco 从报告中排除课程 ...

没有任何作用。

有什么想法吗？

Answer 1

我有这个并且它可以工作（请注意，

excludes

位于

execution/configuration

中，并且所有内容都位于

pluginManagement

中）：

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>pre-integration-test</id>
                    <goals>
                        <goal>prepare-agent-integration</goal>
                    </goals>
                    <configuration>
                        <destFile>${project.build.directory}/integration-coverage-reports/jacoco-it.exec</destFile>
                        <excludes>
                            <exclude>weblogic/*</exclude>
                        </excludes>
                    </configuration>
                </execution>
                <execution>
                    <id>post-integration-test</id>
                    <phase>post-integration-test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                    <configuration>
                        <dataFile>${project.build.directory}/integration-coverage-reports/jacoco-it.exec</dataFile>
                        <outputDirectory>${project.reporting.outputDirectory}/jacoco-it</outputDirectory>
                        <excludes>
                            <exclude>my/company/package/db/entity/**/*.class</exclude>
                        </excludes>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</pluginManagement>

Answer 2

根据您共享的示例，POM 文件中的此更改应该有效：

<build>
      <plugins>
            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.8.1</version>
                <executions>
                    <execution>
                        <id>prepare-agent</id>
                        <goals>
                            <goal>prepare-agent</goal>
                        </goals>  
                    </execution>
                </executions>
                <configuration>
                    <excludes>
                        <exclude>my/package/model/**/*.class</exclude>
                        <exclude>my/package/exception/**/*.class</exclude>
                    </excludes>
                </configuration>
            </plugin>
      </plugins>
</build>

<reporting>
        <plugins>
             <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.8.1</version>
                <configuration>
                    <excludes>
                        <exclude>my/package/model/**/*.class</exclude>
                        <exclude>my/package/exception/**/*.class</exclude>
                    </excludes>
                </configuration>
                <reportSets>
                    <reportSet>
                        <reports>
                            <report>report</report>
                        </reports>
                    </reportSet>
                </reportSets>
            </plugin>
        </plugins>
</reporting>

我通常将

prepare-agent

目标和

report

目标放在同一个插件中。这有助于我将排除包仅放在一个部分下。这就是我的 pom 文件的样子：

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

            <configuration>
                <excludes>
                    <exclude>my/package/model/**/*.class</exclude>
                    <exclude>my/package/exception/**/*.class</exclude>
                </excludes>
            </configuration>

            <executions>
                <execution>
                    <id>prepare-agent</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>  
                </execution>
                <execution>
                    <id>post-unit-test</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Answer 3

查看代码，似乎排除项根本不遵循任何像 Maven/Ant FileSet 这样的语法 - 但很简单：

• per https://www.jacoco.org/jacoco/trunk/doc/prepare-agent-mojo.html，仅支持

  *

  和

  ?

  ，
• 在https://github.com/jacoco/jacoco/blob/master/jacoco-maven-plugin/src/org/jacoco/maven/RuleConfiguration.java#L61中用冒号连接，
  • 至于 https://www.jacoco.org/jacoco/trunk/doc/agent.html 更明显的是其中也没有 Maven/Ant FileSet 机制，
• 然后，在 https://github.com/jacoco/jacoco/blob/master/org.jacoco.report/src/org/jacoco/report/check/Rule.java
  • 与 https://github.com/jacoco/jacoco/blob/master/org.jacoco.core/src/org/jacoco/core/runtime/WildcardMatcher.java 匹配
    • 哪个代码只是将它们转换为正则表达式，通过替换：
      • 带点星号的星号可匹配任意数量的任意字符，
      • 带有单个点的问号可匹配任何单个字符，
      • 任何其他带有正则表达式引用的内容，例如一个点只匹配一个实际的点。
    • 然后，这些正则表达式显然会应用于斜杠串联的源路径和使用

      https://github.com/jacoco/jacoco/blob/master/org.jacoco 中的 

      checkRules 方法时的限定名称。报告/src/org/jacoco/report/check/BundleChecker.java

因此，显然路径被处理为简单字符串，并且任何

**

或

**/*

或

*/*

必须完全冗余。尚未根据经验测试此说法。
