gradle编译错误No signature of method:

• Where:
  Build file ‘/Users/bobsha/Workplace/caixiao/huoban_rn/supplier_app/android/app/build.gradle’ line: 106

• What went wrong:
  A problem occurred evaluating project ‘:app’.
  No signature of method: org.gradle.api.internal.plugins.DefaultExtraPropertiesExtension.call() is applicable for argument types: (build_1hddienakt3715u99hblmmj91 runclosure1 r u n c l o s u r e 1 _closure4 closure12)values:[build1hddienakt3715u99hblmmj91 c l o s u r e 12 ) v a l u e s : [ b u i l d 1 h d d i e n a k t 3715 u 99 h b l m m j 91 _run_closure1 closure4 c l o s u r e 4 _closure12@17e31936]
  Possible solutions: wait(), any(), wait(long), has(java.lang.String), any(groovy.lang.Closure), each(groovy.lang.Closure)

报错如上网上没有找到原因，最后发现是

def config = rootProject.ext

android {
    signingConfigs {
        config {
            storeFile file("supplyer.jks") //签名文件路径
            storePassword "Supplyer357"
            keyAlias "key"
            keyPassword "Supplyer357"  //签名密码
        }
    }

有两个config重名了，改了就好了。。。
