maven - 运行时遇到 Jacoco Method too large Error

Question

对于 drools 库中的方法，jacoco 面临方法太大错误，如何解决？我还尝试将 **DRL6Lexer.class 添加到 jacoco 中的排除项，但它没有用。我还能如何解决这个问题。

错误:

Answer 1

使用 Jacoco 任务扩展(一个扩展 jacoco 注入(inject)到类型为 Test 的每个任务)，您可以排除有问题的 DRL6Lexer 类。

对我来说，这在 gradle 中很有效。

test {
        jacoco{
            excludes = ['org/drools/**/*']
        }
        useJUnitPlatform()
        finalizedBy jacocoTestReport
    }
