构建弹簧框架源代码遇到错误

Question

我通过使用git clone命令从github中获取弹簧框架源代码。当我通过在源代码目录中使用gradle build来构建源代码时，需要很长时间才能下载依赖项并编译java代码，但是发生异常失败。输出如下。

:spring-webmvc-portlet:sourcesJar UP-TO-DATE 
:spring-webmvc-tiles2:javadoc SKIPPED 
:spring-webmvc-tiles2:javadocJar SKIPPED 
:spring-webmvc-tiles2:sourcesJar SKIPPED 
:spring-websocket:javadoc UP-TO-DATE 
:spring-websocket:javadocJar UP-TO-DATE 
:spring-websocket:sourcesJar UP-TO-DATE 
:distZip 

FAILURE: Build failed with an exception. 

* What went wrong: 
Failed to capture snapshot of input files for task 'distZip' during up-to-date c 
heck. See stacktrace for details.

BUILD FAILED 

Total time: 20.861 secs 

错误指示文件spring-framework-4.3.0.BUILD-SNAPSHOT-schema.zip不found.I不知道为什么没有找到这个文件，它应该由distZip任务创建，但事实并非如此。 我google了这个问题，但没有发现任何关于这个问题。

我已经解决了这个问题，恶魔是路径分隔符。因为这个命令在Windows上运行。 从

task schemaZip(type: Zip) { 
     group = "Distribution" 
     baseName = "spring-framework" 
     classifier = "schema" 
     description = "Builds -${classifier} archive containing all " + 
      "XSDs for deployment at http://springframework.org/schema." 
     duplicatesStrategy 'exclude' 
     moduleProjects.each { subproject -> 
      def Properties schemas = new Properties(); 

      subproject.sourceSets.main.resources.find { 
       it.path.endsWith("META-INF/spring.schemas") 
      }?.withInputStream { schemas.load(it) } 

      for (def key : schemas.keySet()) { 
       def shortName = key.replaceAll(/http.*schema.(.*).spring-.*/, '$1') 
       assert shortName != key 
       File xsdFile = subproject.sourceSets.main.resources.find { 
        it.path.endsWith(schemas.get(key)) 
       } 
       assert xsdFile != null 
       into (shortName) { 
        from xsdFile.path 
       } 
      } 
     } 
    } 

修改schemaZip任务定义

task schemaZip(type: Zip) { 
     group = "Distribution" 
     baseName = "spring-framework" 
     classifier = "schema" 
     description = "Builds -${classifier} archive containing all " + 
      "XSDs for deployment at http://springframework.org/schema." 
     duplicatesStrategy 'exclude' 
     moduleProjects.each { subproject -> 
      def Properties schemas = new Properties(); 

      subproject.sourceSets.main.resources.find { 
       it.path.endsWith("META-INF\\spring.schemas") 
      }?.withInputStream { schemas.load(it) } 

      for (def key : schemas.keySet()) { 
       def shortName = key.replaceAll(/http.*schema.(.*).spring-.*/, '$1') 
       assert shortName != key 
       File xsdFile = subproject.sourceSets.main.resources.find { 
        it.path.endsWith(schemas.get(key).replaceAll('\\/','\\\\')) 
       } 
       assert xsdFile != null 
       into (shortName) { 
        from xsdFile.path 
       } 
      } 
     } 
    }
