发布Grails 3插件时的NullPointerException [英] NullPointerException when publishing a Grails 3 plugin

问题描述

我正在尝试发布这个Grails 3 插件给Bintray ，请遵循本指南中的步骤。最后一步是运行

I'm trying to publish this Grails 3 plugin to Bintray, by following the steps in this guide. The final step is to run

gradle bintrayUpload

在项目根目录下的命令行上执行。当我这样做时，我收到以下错误消息：

on the command-line from the project root dir. When I do this, I get the following error message

FAILURE: Build failed with an exception.

* What went wrong:
java.lang.NullPointerException (no error message)

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

* Exception is:
java.lang.NullPointerException

    at com.jfrog.bintray.gradle.BintrayPlugin$_apply_closure2.doCall(BintrayPlugin.groovy:88)

问题的原因是什么？

根据以下建议，我做了以下 build.gradle 中的变化

Following the suggestions below, I've made the following changes in build.gradle

• 将bintray插件更新至版本1.2


• 已将组org.grails.plugins更改为组domurtag.plugins
$ b

• updated the bintray plugin to version 1.2
• changed group "org.grails.plugins" to group "domurtag.plugins"

失败：构建失败，出现异常。

FAILURE: Build failed with an exception.

• 发生了什么问题：执行任务'bintrayUpload'失败。
  • What went wrong: Execution failed for task ':bintrayUpload'.

    
    

    无法创建包'grails / plugins / org.grails.plugins：grails-simple-captcha'：HTTP / 1.1
    403 Forbidden [message：forbidden]

  
  

  
  

  我已经添加了这些环境变量
  
  

  I've added these environment variables

  BINTRAY_USER=domurtag
  BINTRAY_KEY=my_api_key
  

  错误消息表明403的原因是因为试图将插件发布到 grails / plugins 存储库（我无权访问） ，但我不知道为什么会发生这种情况？

  The error message suggests that the reason for the 403 is because an attempt is being made to publish the plugin to the grails/plugins repository (which I don't have access to), but I don't know why this is happening?

  推荐答案

  我看到了我的Gradle构建完全相同的堆栈跟踪。我的Gradle构建脚本使用 com.jfrog.bintray version 1.1。升级到版本1.2后，构建成功运行。

  I saw the exactly same stacktrace for my Gradle builds. My Gradle build script made use of com.jfrog.bintray version 1.1. After upgrading to version 1.2 the build runs successfully.
