使用JaCoCo创建代码覆盖报告时出错

Question

我正在尝试使用JaCoCo为代码覆盖添加报表生成。该项目使用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>

surefire插件如下：

         <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>

但是在跑步的最后

mvn清洁包

我犯了这样的错误：

[错误]无法执行目标组织。jacoco:jacocomaven插件：0.7。5.201505241946：项目LMS的报告（report）：JaCoCo测试报告生成中出现错误。创建报告时出错：无效的文字/长度代码-

问题是，在另一个项目上，同样的东西就像一个符咒。我无法在网上找到解决方案。有人有什么想法吗？

使用-e开关，我得到以下错误：

Answer 1

我也曾经面对过这个问题。这似乎与jacoo分析器无法解析某些资源（可能是git子模块或其中的zip/binary）有关。只需忽略此任务的resources文件夹的路径即可修复此问题。
