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

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:\TDDownload\groovy-src-2.3.8\groovy-2.3.8\gradle\pomconfigurer.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
Deployment environment set to Bintray

BUILD FAILED

Stopped 0 compiler daemon(s).
Received result DaemonCommandResult[type=CommandFailure, value=http://www.mamicode.com/org.gradle.launcher.exec.ReportedException: org.gradle.internal.exceptions.LocationAwareException>
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:\TDDownload\groovy-src-2.3.8\groovy-2.3.8\README.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:\Users\chenjo\.gradle\wrapper\dists\gradle-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\target\distributions\ 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
