Skipping JaCoCo execution due to missing execution data file
2024-06-03 03:21:37
# 情境分析
今天在为项目集成sonar单元测试覆盖率的过程中，发现了许多问题，在这里记录下，为大家提供一下解决思路# 单测覆盖率执行思路
1. 首先通过maven打包，然后生成测试文件
2. sonar扫描导入maven生成的测试文件，出现单测覆盖率# 可能出现问题的点
1. 可能没有生成测试文件
2. 生成的测试文件可能为空，没有数据# 上面两个问题，如何确定呢？ (通过查看日志)
1. 使用 Surefire 配置破坏 JaCoCo 代理
在maven install打包的日志中，出现如下日志信息
[INFO] Skipping JaCoCo execution due to missing execution data file.或者，不会出现如下信息[INFO] --- jacoco-maven-plugin:0.8.5:prepare-agent (default-prepare-agent) @ sirius ---
[INFO] surefireArgLine set to -javaagent:/builds/situ/situ-java-program/situ-galaxy/sir-server/sir/./.m2/repository/org/jacoco/org.jacoco.agent/0.8.5/org.jacoco.agent-0.8.5-runtime.jar=destfile=/builds/situ/situ-java-program/situ-galaxy/sir-server/sir/target/jacoco.exec,includes=com/situ/sir/**/*,excludes=**/po/**/*:**/config/**/*2. 虽然单个测试类可以运行也没有错，但是maven install打包的时候，run的数字为0
[INFO] Results:
[INFO]
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0# pom文件示例配置 (第一种)<properties><!-- sonar单测扫描 --><jacoco.version>0.8.5</jacoco.version><jacoco.reportPath>${project.basedir}/target/jacoco-ut.exec</jacoco.reportPath>

如果你按照第一种不行，在日志中出现错误情况的第一种
那么可能是Surefire 配置破坏 JaCoCo 代理
请采用第二种方案
# pom文件示例配置 (第二种)<properties><!-- sonar单测扫描 --><jacoco.version>0.8.5</jacoco.version><jacoco.reportPath>${project.basedir}/target/jacoco-ut.exec</jacoco.reportPath>

</plugins>请注意maven依赖也会影响，是否能够检测出单测覆盖率
# 请使用第一个，不要使用第二个1. 第一个
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><version>${springboot.version}</version>
</dependency>2. 第二个
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-test</artifactId><version>${springboot.version}</version>
