could not read 'https://dl.bintray.com/scalding/generic/waroverlay.gradle'
解决方法
https://dl.bintray.com服务停用了，gradle用waroverlay打war失败
我改成这样就行了：
apply plugin:'war'
apply plugin: scaldingspoon.gradle.WarOverlayPlugin
warOverlay {
includeWarJars true
}
buildscript {
repositories {
jcenter()
}
dependencies {
classpath "org.scaldingspoon.gradle:gradle-waroverlay-plugin:0.9.3"
}
}
