今天为了学习 怎样使用 Groovy 写 Groovy 的測试代码, 所以到 http://groovy.codehaus.org/Download 下载了 Groovy 2.3.8 的源码包.
Groovy 是採用 Gradle 作为 构建工具的. 先看我本地的 Gradle 的相关环境:
>gradle -v ------------------------------------------------------------ Gradle 2.2 ------------------------------------------------------------ Build time: 2014-11-10 13:31:44 UTC Build number: none Revision: aab8521f1fd9a3484cac18123a72bcfdeb7006ec Groovy: 2.3.6 Ant: Apache Ant(TM) version 1.9.3 compiled on December 23 2013 JVM: 1.8.0_25 (Oracle Corporation 25.25-b02) OS: Windows 7 6.1 amd64
然后我在加压缩之后的源代码根文件夹下输入 gradle tasks ,
gradle 開始从 jcenter 下载须要的 jar 包,
然后開始编译,
最后出现这个错误:
Detected development environment Deployment environment set to Bintray FAILURE: Build failed with an exception. * Where: Script 'H:TDDownloadgroovy-src-2.3.8groovy-2.3.8gradlepomconfigurer.gradle' line: 10 * What went wrong: A problem occurred evaluating script. > Could not find property 'groovy' on configuration container. * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. BUILD FAILED Total time: 5 mins 7.403 secs
我接着用 gradle tasks --info 命令再跑一遍, 还是出现以下的错误:
Detected development environment

le.encoding=GBK,-Duser.country=CN,-Duser.language=zh,-Duser.variant]}.如何绕过这个错误呢? 难道是我的 Gradle 的版本号问题?
于是我打开文件 H:TDDownloadgroovy-src-2.3.8groovy-2.3.8README.adoc ,
发现里面说到:
To build everything using Gradle (the command below will download Gradle automatically, you do not need to download it first).
./gradlew clean dist于是我就打开 命令行 窗体 到 源代码文件夹下, 键入: gradlew clean dist
我发现这个命令会首先下载一个 gradle-1.12 -all 到本地
C:Userschenjo.gradlewrapperdistsgradle-1.12-all
然后加压缩, 然后在以该版本号下载 jar 包 以及进行 编译, 汇总.... 尽管中间有一些警告, 或是下载 jar 包时网络受阻, 我就中断命令又一次运行几次, 最后 build 成功.

然后我看到 生成的 target 目录 竟然有 500 多 M 字节.
在 项目文件夹 argetdistributions 下, 有例如以下生成的公布文件:
groovy-binary-2.3.8.zip
groovy-docs-2.3.8.zip
groovy-sdk-2.3.8.zip
groovy-src-2.3.8.zip
