Java.lang.IllegalStateException : Failed to parse JaCoCo XML report: jacoco. exec

Question

我正在尝试发布由 Jacoco 插件生成的覆盖率报告 - jacoco.exec。但是我得到了下面提到的 Sonar 和 Jacoco 配置的异常。

SonarCube 版本 6.7.7

我是否缺少 Sonar 或 jacoco 中的任何配置？

Answer 1

java.lang.IllegalStateException: Failed to parse JaCoCo XML report: jacoco.exec
...
Caused by: javax.xml.stream.XMLStreamException: java.nio.charset.MalformedInputException: Input length = 1

报错说明解析XML时发现不支持的字符，文件为 jacoco.exec .
这是因为 jacoco.exec是二进制的，而不是 xml。

另外 Sonar has deprecated the support of jacoco.exec .
建议您关注 coverage-test-data-importing-jacoco-coverage-report-in-xml-format .
从上面的链接:

By default the generated report will be saved under target/site/jacoco/jacoco.xml; this location will be checked automatically by the sonar-jacoco plugin so no further configuration is required. Just launch mvn sonar:sonar as usual and the report will be picked up.
