我使用git clone命令从github获取了spring框架源代码。当我在源代码目录中使用gradle build构建源代码时，下载依赖项和编译java代码需要很长时间，但失败并出现异常。输出如下。

BUILD FAILED

该错误指示未找到该文件spring-framework-4.3.0.BUILD-SNAPSHOT-schema.zip。我想知道为什么找不到这个文件，它应该由distZip任务创建，但它没有。我已经用谷歌搜索了这个问题，但没有发现任何问题。
我已经解决了这个问题，魔鬼是路径分隔符。因为此命令在窗口上运行。从以下位置修改架构 Zip 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))
}
assert xsdFile != null
