gradle 2.3 中的 Jcenter() 异常

Jcenter() exception in gradle 2.3

我在尝试 运行 Soapui 到 gradle 时遇到异常。我正在使用最新的 gradle 2.3

* What went wrong:
A problem occurred evaluating root project 'gradle-builds'.
> Could not find method JCenter() for arguments [] on repository container.

贝洛斯是我的 build.gradle。首先我 运行 没有 task wrapper 给了我同样的异常,然后我添加了 task wrapper 但仍然得到异常。有人可以帮忙吗?

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}
buildscript {
    repositories {
        JCenter()
    }    

    dependencies {
        compile files('C:/.../SoapUI-5.0.0/bin/soapui-5.0.0.jar')
        compile fileTree(dir: "C:/.../SoapUI-5.0.0/lib", include: '*.jar')

        classpath 'com.lv.plugins:soapui-gradle-plugin:VERSION'
    }
}
soapui {
    test {
        projectFile = 'C:/Users/.../soapui-project.xml'
        printReport = true
        junitReport = true
    }

    tool {
        projectFile = 'C:/../soapui-project.xml'
        iface = 'IOrderService'
        tool = 'wsi,axis1,axis2'
    }
}

应该是:

jcenter()
