在 gradle 上使用缓存的依赖项和插件运行黄瓜测试 [英] Run cucumber test with cached dependencies and plugins on gradle

问题描述

我想在一个 gradle 项目上运行一些用黄瓜做的测试，我试图在另一台 PC 上运行这个测试(网络访问受限)，所以我复制/粘贴了 下的所有内容~./gradle/caches 和 build, src 和 build.gradle 等项目文件，并将所有内容放在与原始文件相同的位置

Hi I want to run a few test made with cucumber on a gradle project, I was trying to run this test's on another PC (with limited network access) so I copy/pasted everything that was under ~./gradle/caches and the project files like build, src and build.gradle and placed everything on the same place as the original

所以一旦我准备好一切，我就运行了

So once I got everything in place I ran this

  gradle --no-daemon --offline cucumber

我失败了

> Could not resolve all dependencies for configuration ':classpath'.
   > Could not download gradle-cucumber-plugin.jar (com.github.samueltbrown:gradle-cucumber-plugin:0.9): No cached version available for offline mode

奇怪的是我在缓存目录中有这个文件

The odd thing is that I have the file on the caches directory

~/.gradle/caches/modules-2/files-2.1/com.github.samueltbrown/gradle-cucumber-plugin/0.9/7b65c67654715025eed1924
0c4f7defbef9645e0# ls
gradle-cucumber-plugin-0.9.jar

仅供参考，我没有像我希望的那样使用 gradle/java 的经验，所以任何类型的建议都会很棒，这是 build.gradle 上需要"插件的地方

FYI, I don't have the kind of experience with gradle/java as I would like so any kind of suggestion would be great, this is where the plugin is "required" on the build.gradle

plugins {
  id "com.github.samueltbrown.cucumber" version "0.9"
}

谢谢

推荐答案

看到这个开放的 Gradle issue

Gradle 缓存目前并不完全可移植.如果 .gradle 文件夹的绝对路径在两台机器上完全相同，它确实有效.如果两台机器的用户名不同，~/.gradle的绝对路径是不一样的！

Gradle cache isn't exactly portable currently. It does work, if the absolute path of the .gradle folder is exactly the same on both machines. The absolute path of ~/.gradle is not the same if the username on both machines is different!

有几种方法可以解决这个问题，按照所需的努力程度，最少到最多:

There are a few ways you can get around this, in order of effort required, least to most:

如果这在您的网络受限机器上是可能的，在没有离线标志的情况下运行一次，将不会再次下载依赖项，但校验和 - 更重要的是缓存现在已经过验证并适合与 一起使用 -离线标志.

If this is possible on your network limited machine, run without offline flag once, the dependencies will not be downloaded again, but checksums are - and more importantly the cache is now validated and suitable for use with the --offline flag.

通过在两台机器上设置 GRADLE_USER_HOME 将 gradle 缓存文件夹移动到类似 /tmp/.gradle 的位置，然后在机器之间复制 gradle 缓存.

Move gradle cache folder to something like /tmp/.gradle by setting GRADLE_USER_HOME on both machines and then copy gradle cache between machines.

在联网的机器上，使用 gradle 任务将所有依赖项导出到文件系统文件夹.将文件夹复制到另一台机器上，并在第二台机器上使用 flatdir 存储库.

On the network connected machine, use a gradle task to export all dependencies to a filesystem folder. Copy the folder over to the other machine, and use a flatdir repo on the second machine.

repositories {
  flatDir {
    dirs 'lib' //folder containing dependencies
  }
}

(您也可以导出到 maven 格式的存储库而不是 flatdir.参见 https://stackoverflow.com/a/13396776/1174024)

(You could also export to a maven format repo instead of flatdir. See https://stackoverflow.com/a/13396776/1174024)

根据我的经验，Maven 的 .m2 文件夹更便携.创建一个具有相同依赖项的 maven 项目，将依赖项缓存到 .m2 中，然后将 .m2 复制到第二台机器上.在第二台机器上添加 mavenLocal() 作为 repo.

In my experience Maven's .m2 folder is far more portable. Create a maven project with the same dependencies, cache dependencies into .m2 and then copy .m2 over to the second machine. On the second machine add mavenLocal() as a repo.
