使用JaCoCo创建代码覆盖率报告时出错

Question

我正在尝试使用JaCoCo为代码覆盖添加报告生成.该项目正在使用Maven,所以我有jacoco maven插件配置如下:

         <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>${jacoco.maven.plugin.version}</version>
            <executions>
                <execution>
                    <id>prepare-agent</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                    <configuration>
                        <destFile>${basedir}/target/coverage-reports/jacoco-unit.exec</destFile>
                    </configuration>
                </execution>
                <execution>
                    <id>report</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                    <configuration>
                        <dataFile>${basedir}/target/coverage-reports/jacoco-unit.exec</dataFile>
                        <outputDirectory>${basedir}/target/jacoco</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>

还有像这样的surefire插件:

         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>${maven.surefire.plugin.version}</version>
            <configuration>
                <argLine>${argLine} -XX:-UseSplitVerifier</argLine>
                <printSummary>true</printSummary>
                <excludes>
                    <exclude>**/selenium/**/*.java</exclude>
                <excludes>
            </configuration>
        </plugin>

但是在跑步结束时

mvn清洁包

我收到这样的错误:

[错误]无法执行目标org.jacoco:jacoco-maven-plugin:0.7.5.201505241946:项目LMS上的报告(报告):JaCoCo测试报告生成中发生错误.创建报告时出错:无效的文字/长度代码 - > [帮助1] [错误] [错误]要查看错误的完整堆栈跟踪,请使用-e开关重新运行Maven.[ERROR]使用-X开关重新运行Maven以启用完整的调试日志记录.[错误] [错误]有关错误和可能的解决方案的更多信息,请阅读以下文章:[错误] [帮助1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

问题是,在另一个项目中,同样的事情就像一个魅力.我在网上找不到解决方案.有人有什么想法吗？

使用-e开关我收到以下错误:

Answer 1

我也曾经遇到过这个问题。这似乎与 Jacoco 分析器无法解析某些资源（大概是 git 子模块或其中的 zip/二进制文件）有关。只需忽略此任务的资源文件夹的路径即可解决问题。
