我在我的项目中使用了龙目岛,但我的同事不同意使用它,他的理由是(来自lombok文件的争议)

这两个项目Lombok都利用非公共API来完成他们的巫术.这意味着使用后续IDE或JDK版本可能会破坏Project Lombok的风险.

但这是一篇2010年写的非常古老的文档,也许现在已经解决了这个问题,所以我想知道Lombok是否支持Java 9并且它仍然使用非公共API:s？

我创建了一个 Cucumber 功能文件和步骤文件，然后单击功能文件的“运行配置”，我在控制台中看到以下内容。我怎么解决这个问题？

目前我有一个执行运行程序的任务，比如

task runApp(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath

    main = 'com.eonmux.somepackage'

    jvmArgs '-Xmx4096m'
}

我正在尝试将 --add-opens 添加到 JVM 参数列表中，以便允许从我的 gradle 包进行反射访问

就像是

task runApp(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath

    main = 'com.eonmux.somepackage'

    jvmArgs '-Xmx4096m','--add-opens java.base/jdk.internal.loader=ALL-UNNAMED'
}

但是，这会出现以下错误，指出命令行选项无法识别

2020-12-09T16:30:56.285-0500 [INFO] [org.gradle.process.internal.DefaultExecHandle] Successfully started process 'command 'C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-openj9\bin\java.exe''

这是我的第一个黄瓜项目，我在设置所有内容时遵循了教程。一切似乎都是一样的，但出于某种原因我得到了这个：

java.lang.ExceptionInInitializerError。\n原因：java.lang.reflect.InaccessibleObjectException：无法使字段私有最终java.util.Comparator java.util.TreeMap.comparator可访问：模块java.base不“打开java.util”到未命名模块@74ad1f1f

知道如何解决这个错误吗？

下面我发布了控制台中出现的所有内容以及我的 pom 文件，以防我的依赖项出现问题，尽管教程的 pom 文件中的人员是相同的。

这就是我的控制台中显示的所有内容。

java.lang.reflect.InaccessibleObjectException尝试 Mock 一个对象一段时间

Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @238e0d81

我已经使用 java 16 启动了一个项目，但项目中到处都出现错误：

An error has occurred. See error log for more details.
Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @6dfcffb5

看来我从不同版本的 java 获得的代码在这个特定版本中不起作用。知道我需要在 pojo 类中更改什么吗？我的应用程序中只有 1 个 pojo，因为它是微服务。

谢谢。

Hibernate是否已准备好使用Java 9的可用版本？

我记得我已经尝试过但失败了.不幸的是我不记得具体原因.

顺便说一下,Hibernate Validator 5.2.3已经可以与Java 9一起使用了.

运行测试时出现错误，我无法理解为什么会出现此错误，此代码在 java 8 中运行良好，而在 java 17 中运行时出现错误。谷歌搜索了这个错误，但没有发现任何有用的东西。请帮助我理解这个错误。提前致谢：）

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:
