运行时面临Jacobo方法过大错误

Question

面对方法太大对于drools库中的方法，来自jacoco的错误，如何解决？我还尝试在jacoco中的exlucdes中添加**DRL6Lexer.class，但没有成功。否则我该如何解决这个问题。

错误：

Answer 1

使用Jacobo任务扩展(Jacoco为每个任务注入的扩展，类型为Test)，可以排除有问题的DRL6Lexer类。

对我来说，这很有效。

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