针对JDK 9模块的TestNG测试执行导致InaccessibleObjectException

Question

我正在尝试将以下库转换为Java 9模块:https://github.com/sskorol/test-data-supplier

遵循本指南:https://guides.gradle.org/building-java-9-modules

经过一些操作和重构(无法管理lombok问题,所以只是临时删除它),我有以下module-info.java:

module io.github.sskorol {
    exports io.github.sskorol.core;
    exports io.github.sskorol.model;

    requires testng;
    requires vavr;
    requires streamex;
    requires joor;
    requires aspectjrt;
}

它甚至可以在测试跳过的情况下进行编译/构建.但是,当我尝试运行测试任务时,我收到以下异常:

这对我来说似乎有点混乱,因为io.github.sskorol.testcases是src/test/java的一部分,并且没有用于测试的模块信息.所以我无法将此包导出到TestNG.假设ObjectFactoryImpl中的TestNG反射用法的根本原因是针对测试类.

有谁知道如何解决它？

环境:JDK 9(版本9 + 181),Gradle 4.1,TestNG 6.11

Answer 1

假设TestNG中的根本原因反映在ObjectFactoryImpl测试类中.

这是两个原因之一,是的.另一个是,显然,Gradle将您的测试作为一个模块运行.正如您所指出的,您的测试没有模块描述符.Gradle可以--patch-module用来将测试添加到包含生产代码的模块中.

这个问题和答案提供了大量的背景信息和可能的修复.作为短期修复,我建议添加opens io.github.sskorol.testcases到生产代码的模块描述符中.从它的名字来看,我猜想还没有这样的软件包,所以你要么重命名要么添加一个虚拟类(我更喜欢前者).

我也会把这个问题带到Gradle邮件列表或bug跟踪器.除非我们忽略了某些事情(完全可能),否则Gradle的行为非常不幸,因为它需要根据测试代码的需要调整生产代码的模块描述符.
