gradle 编译也太严格了吧,使用过期的 api、方法返回值的范型跟方法签名不一样...(自动推断不可以?)


总之解决方案:

    tasks.withType(JavaCompile) {
     // Try to turn them all off automatically
     options.compilerArgs << '-Xlint:none'
     options.compilerArgs << '-nowarn' // same as '-Xlint:none'

     // Turn them off manually
     options.compilerArgs << '-Xlint:-auxiliaryclass'
     options.compilerArgs << '-Xlint:-cast'
     options.compilerArgs << '-Xlint:-classfile'
     options.compilerArgs << '-Xlint:-deprecation'
     options.compilerArgs << '-Xlint:-dep-ann'
     options.compilerArgs << '-Xlint:-divzero'
     options.compilerArgs << '-Xlint:-empty'
     options.compilerArgs << '-Xlint:-fallthrough'
     options.compilerArgs << '-Xlint:-finally'
     options.compilerArgs << '-Xlint:-options'
     options.compilerArgs << '-Xlint:-overloads'
     options.compilerArgs << '-Xlint:-overrides'
     options.compilerArgs << '-Xlint:-path'
     options.compilerArgs << '-Xlint:-processing'
     options.compilerArgs << '-Xlint:-rawtypes'
     options.compilerArgs << '-Xlint:-serial'
     options.compilerArgs << '-Xlint:-static'
     options.compilerArgs << '-Xlint:-try'
     options.compilerArgs << '-Xlint:-unchecked'
     options.compilerArgs << '-Xlint:-varargs'
}

上面两行是关闭全部的警告信息,下面是针对不同的选项进行手动关闭。
