Jacoco 0.8.7显示代码覆盖率为零

Question

我看到詹金斯插件中的代码覆盖率为零。我在客户端服务器模式下使用 Jacoco 0.8.7。客户端是詹金斯，服务器（此处存在jaco代理jar）是一个VM。当我使用旧版本的jaco 0.7.4时，这并没有发生。

Jenkins CI插件配置是这样的。使用ant和maven组合来转储exec文件。

Answer 1

“1字节UTF-8序列的无效字节1”；建议使用错误的文件格式，通常是BOM。检查使用文件是否正确。

您可以指定文件/路径/收件人/文件名.txt。第一种可能是当存在 BOM（字节顺序标记）时您会看到的内容，这将产生错误：1 字节 UTF-8 序列的字节 1 无效。

第二个是同一个文件，没有BOM转换。

$ file jacoco.exec
jacoco.exec: Unicode text, UTF-8 (with BOM) text

$ file jacoco.exec
jacoco.exec: ASCII text

一旦你确定格式不正确，就要由你来决定如何以这种方式结束以及如何修复。很可能是在操作系统之间移动文件的转换问题。

您是在混合环境中运行还是已经从Win转移到Linux（或Mac；不知道）？

顺便说一下：Jacoco
Release 0.7.4（2015/02/26）
Release 0.8.7（2021/05/04）
包含了很多更改，从Java8到Java18支持，到maven 3的更改，从ASM 5.0.1到ASM 9.3，很难说为什么它不再接受，假设你改变的只是Jacoco版本（从来都不是一件事）。
