先讲基本步骤，如下：

  1. 去GitHub中下载spring framework的源码，https://github.com/spring-projects/spring-framework/releases
  2. 下载3.2.X其中的一个版本; 
  3. 安装Gradle软件，官网下载，解压即可，设置GRADLE_HOME,和PATH。
  4. 命令行中运行gradle -v，检查一下是否正确安装配置；
  5. 命令行中运行spring framework根目录下的import-into-eclipse.bat
  6. 连续两次回车，就可以开始自动构建；
  7. 中间出现停止不前的情况里，按ctrl+c终止，再运行就可以进行下去；
  8. 过程需要花些时间（几个小时都有可能），视下载各种依赖jar包和dom文件的速度而定；
  9. 在Eclipse菜单File->import选择General下面的Exsiting projects into workspace，这样就导入完成了。

如果你按上述步骤能一次成功的话，那不仅是你运气，而且RP极高。反正我没有，而且还折腾了好多次才成功能。

 

问题有以下几个：

 

  • 问题一：spring-framework-4.0.0.M3要用jdk1.8

如果你习愦于什么都下最新版的，那么你肯定想都没想就下了spring-framework-4.0.0.M3，而且又那么不好采，正好没看README，那么问题马上就来了，直接报"-XX:MaxMetaspaceSize=1024m"及"could not create the java Virtual machine"的错误。

查看build.gradle和gradlew.bat中，可以找出原因：

build.gradle中：

Java代码  技术分享图片
  1. compileJava {  
  2.         sourceCompatibility=1.6  
  3.         targetCompatibility=1.6  
  4.     }  
  5.     compileTestJava {  
  6.         sourceCompatibility=1.8  
  7.         targetCompatibility=1.8  
  8.     }  

 可以看出这个版本的test代码要求用1.8。

gradlew.bat中

  1. set GRADLE_OPTS=-XX:MaxMetaspaceSize=1024m -Xmx1024m -XX:MaxHeapSize=256m %GRADLE_OPTS%  

 其中-XX:MaxMetaspaceSize是1.8的写法。

所以如果下载的是4.0的版本，最好把jdk也升级到1.8，要不就下载一下3.2.x的版本就好了。

 

  • 问题2：在build过程中，出现heap内存溢出情况

错误信息如下：

那就把gradlew.bat的内存设置调大一点，我做实验时，机器的内存是8G、64位系统，直接使用

set GRADLE_OPTS=-XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=1024m %GRADLE_OPTS%

（我下载的是spring-framework-3.2.1.RELEASE版本，jdk1.7）

 

  • 问题3：gradle命令的使用

在spring源码的根目录下，提供gradlew.bat和

import-into-eclipse.bat这两个命令，都可以build源码，但如果使用前者就不会生成eclipse的环境需要的一些文件，如下图所示：

另外，在使用import-into-eclipse.bat这个命令build时，可能会遇到一个问题，错误日志如下：

 从日志中可以看出是在build spring-webmvc-tiles3项目时，生成eclipse的.classpath文件时出错，打开其它正常导入的项目的.classpath看下这个文件包含了哪些信息，如打开spring-aop项目的：

 而spring-webmvc-tiles3下根本就没有.classpath的影子，没得比较，虽然上面的错误日志的E文都认识，但还是看不出它在讲什么，不过大体能看得出是依赖出了问题，那只能是想办法顺藤摸瓜了。重新打开build.gradle，找到有关spring-webmvc-tiles3项目的描述，如下：

 打开C:/Users/so/.gradle/caches/artifacts-15/filestore，挨个依赖进行检查，jar包倒是最下载下来了，但是"org.apache.tiles:tiles-jsp:3.0.1"、"org.apache.tiles:tiles-extras:3.0.1"、"org.apache.tiles:tiles-el:3.0.1"三个却没有下载到source，其它包都有jar、pom、source三个目录，这三个没有source目录，只有jar、pom目录，问题应该是出现在这里。

 

后来终于让我找到了这么一个东西：http://issues.gradle.org/browse/GRADLE-1157，正好证实我前面的猜想，所以按照issue中的解决办法，在build.gradle中加上如下部分：

Java代码  技术分享图片
  1. eclipseClasspath {  
  2.             downloadSources = false; // required for eclipseClasspath to work  
  3. }  

 关于spring-webmvc-tiles3项目的脚本、就变成这样了：

  30.     eclipseClasspath {  
  31.             downloadSources = false; // required for eclipseClasspath to work  
  32.     }  
  33. }  

 重新运行命令，这一次终于让我看到了BUILD SUCCESSFUL的字样了……

 

成功build完成后，可以看到spring目录下的spring-webmvc-tiles3项目也正常生成了导入eclipse需要的文件。打开.classpath查看一下：

 果然没有sourcepath的信息。

 

折腾了那么久，终于到了可以看一下成果的时候了。

Spring Tool Suite说简单一点就是Spring家的eclipse，去官网下一个最新版，安装上。

打开STS，菜单File->import选择General下面的Exsiting projects into workspace，勾选要导入的子项目，确定即可。
