the error indicates file spring-framework-4.3.0.build-snapshot-schema.zip not found.i wondered why file not found,it should created distzip task doesn't. have googled problem not found question this.

i have resovled problem,the devil path separator.because command runs on windows. modify schemazip task definition from

task schemazip(type: zip) {         group = "distribution"         basename = "spring-framework"         classifier = "schema"         description = "builds -${classifier} archive containing " +             "xsds deployment @ 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) }              (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                 (shortname) {                     xsdfile.path                 }             }         }     }
