Question

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，下载依赖项并编译java代码需要很长时间，但是因异常而失败。输出如下。

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

:distZip

错误表示找不到文件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，但事实并非如此。我搜索了这个问题，但没有发现任何问题。

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

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))
                }
                assert xsdFile != null
                into (shortName) {
                    from xsdFile.path
                }
            }
        }
    }

到

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
                }
            }
        }
    }
