gradle - gradle构建在类路径中不包含jar

Question

大家

这是构建脚本

apply{
    plugin 'java'
}

    sourceCompatibility=1.5

    List spring = ["org.springframework:spring-webmvc:$springVersion@jar",
                   "org.springframework:spring-orm:$springVersion@jar",
                   "org.springframework:spring-context-support:$springVersion@jar"]

    List spring_js = [ "org.springframework.webflow:spring-js:2.0.7.RELEASE@jar",
                       "org.apache.ibatis:com.springsource.com.ibatis:2.3.4.726@jar",
                       "com.caucho:com.springsource.com.caucho:3.2.1@jar",
                       "org.apache.axis:com.springsource.org.apache.axis:1.4.0@jar",
                       "javax.wsdl:com.springsource.javax.wsdl:1.6.1@jar"]

    configurations {
        compile {
            description = 'compile classpath'
            transitive = true
        }
        runtime {
            extendsFrom compile
        }
    }

    def localMavenRepo = 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath

    repositories{
        mavenCentral()
        maven{
            url localMavenRepo
        }
    }

    dependencies{
        compile spring, spring_js, 'commons-fileupload:commons-fileupload:1.2.1','org.apache.struts:com.springsource.org.apache.struts:1.2.9',
                'javax.xml.rpc:com.springsource.javax.xml.rpc:1.1.0','org.apache.commons:com.springsource.org.apache.commons.dbcp:1.2.2.osgi',
                'commons-io:commons-io:1.3.2','hsqldb:hsqldb:1.8.0.7','org.apache.tiles:tiles-jsp:2.2.0','org.tuckey:urlrewritefilter:3.1.0',
                'org.apache.tiles:tiles-core:2.2.0'
        runtime 'javax.servlet:jstl:1.2','org.aspectj:aspectjweaver:1.6.5','javax.servlet:servlet-api:2.5','javax.servlet.jsp:jsp-api:2.1'
        testCompile 'junit:junit:4.6'
    }

jar 存在于本地Maven存储库中，但是当我运行gradle --info clean build时，构建失败，并出现诸如以下错误

如果我使用Maven运行相同的构建，它将从本地存储库中提取所有依赖项并成功进行编译。我也尝试了--refresh-dependencies开关，但没有帮助。

如本杰明所说，您可能缺少依赖项声明。请注意，使用@jar会禁用传递依赖项解析。 @jar的意思是“我只想要这个Jar，而不想要它的POM中声明的任何依赖项”。

声明本地Maven存储库的首选方法是repositories { mavenLocal() }。除非您在本地Maven存储库中安装了其他版本，并且从该版本中拉出该版本，否则既不建议也没有必要声明mavenLocal()。如果它们的校验和匹配，Gradle足够聪明，可以自动从本地Maven存储库中窃取Jar(避免下载它们)。

您的configurations块可以完全删除。所有这些已经由java插件配置了。
