Badass 运行时建议模块 NPE 问题答案

【问题标题】：Badass runtime suggestModules NPE problemBadass 运行时建议模块 NPE 问题
【发布时间】：2020-02-19 19:33:57
【问题描述】：

我正在尝试使用适用于 OpenJDK13 的 badass 运行时插件创建安装程序。我有一个简单的开发应用程序可以做到这一点，它可以按预期在 Windows 上安装和运行。然后我将我的 gradle.build 文件移植到主应用程序并开始进行一些修改以使用它。在开发应用程序中，我使用了建议模块任务，它对于为运行时任务创建必要的模块列表非常有用。当我在我的主应用程序上使用SuggestModules 任务时，我得到以下异常，就像badass 运行时插件查找项目时项目值为空一样？：

gradle suggestModules --stacktrace
> Task :suggestModules FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':suggestModules'.
> java.lang.NullPointerException (no error message)

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':suggestModules'.

【解决方案1】：

看起来项目中包含了一个无效的依赖项，至少对于插件来说是这样，因为它无法处理它。

TL;DR：'com.sun.xml.ws:jaxws-ri:2.3.2' 包含 zip，而不是 jar，插件无法找到有效的工件。

长答案

在不克隆和调试插件的情况下，您可以通过这种方式找出出现空指针异常的原因。

异常显示：

java.lang.NullPointerException
    at org.beryx.runtime.util.Util.getArtifact(Util.groovy:75)
    at org.beryx.runtime.util.SuggestedModulesBuilder.getProjectModules(SuggestedModulesBuilder.groovy:37)

所以如果你去插件repository 并检查这两个类：

第一个使用运行时类路径依赖项，在第二个中查找每个工件的工件文件。

所以我根据源代码创建了这个任务：

task myTask () {     
    def deps = project.configurations['runtimeClasspath'].resolvedConfiguration.firstLevelModuleDependencies;
     for (d in deps) { 
        println "dep: $d with $d.moduleArtifacts" 
        def artifact = d.moduleArtifacts.find { it.classifier } ?: d.moduleArtifacts[0]
         if (artifact != null) { 
            println "f: $artifact  -> ${artifact.file}"         
        } else {
             println "f is null" 
        }     
    }
 }

如果你运行这个任务：

./gradlew myTask

对于每个有效的依赖项，您将获得如下信息：

dep: javax.annotation:javax.annotation-api:1.3.2;runtime with [javax.annotation-api.jar (javax.annotation:javax.annotation-api:1.3.2)]
f: javax.annotation-api.jar (javax.annotation:javax.annotation-api:1.3.2)  -> C:\Users\<user>\.gradle\caches\modules-2\files-2.1\javax.annotation\javax.annotation-api\...

但是，对于com.sun.xml.ws:jaxws-ri:2.3.2，您会得到：

dep: com.sun.xml.ws:jaxws-ri:2.3.2;runtime with []
f null

那么这个依赖有什么问题呢？

让我们在Maven Central 上看看：你会发现“神器”原来是一个 zip：jaxws-ri-2.3.2.zip。

因此，插件不知道如何处理它，因为它期待常规 jars...

解决方案

为避免处理 zip，请暂时从运行时类路径中删除此依赖项。

由于您的项目会中断，您可以这样做：

compileOnly 'com.sun.xml.ws:jaxws-ri:2.3.2'

终于可以运行了：

./gradlew suggestModules

并得到一个有效的结果：

modules = [
'java.logging',
'java.xml',
'java.desktop',
'jdk.unsupported',
'jdk.jfr',
'jdk.unsupported.desktop',
'java.datatransfer',
'java.scripting']

当然，您仍然会丢失排除依赖项中的部分。

报告问题

您还应该将问题报告给插件issue tracker，链接到这篇文章。

Utils:getArtifact 中的快速修复，例如：

artifact != null ? artifact.file : null

将阻止 NPE，但可能有更好的方法来提取 zip 并检查它可能包含的 jar。

【讨论】：

这确实是问题所在。我将该依赖项切换到 CompileOnly 并能够获取模块列表，这反过来导致 jpackage 制作了完整的工作安装程序。何塞的一个伟大而全面的回答。我会报告这个问题。
很高兴它成功了。不要忘记将答案标记为已接受，因为以后可能对其他人有用。
