lib.* 中依赖 support-annotations-27.0.2，代码中访问 @ColorInt 等，编译插件时出现 错误: 程序包android.support.annotation不存在

我在 lib.* 中引用了 compile 'com.android.support:support-annotations:27.0.2'，在代码调用的时候，出现 @ColorInt、@IntDef 等方式调用，然后在编译插件的时候出现如下错误：

同样的依赖库，如果放在 app+* 或者改成以 jar 的方式引用，不会出现上述编译问题。

环境说明：

buildscript

{
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'net.wequick.tools.build:gradle-small:1.2.0-beta3'
    }
}

apply plugin: 'net.wequick.small'

small {
    buildToAssets = false
    aarVersion = '1.3.0-beta5'
    android {
        compileSdkVersion = 25
        buildToolsVersion = "25.0.2"
        supportVersion = "25.1.0"
    }
}

这个问题的原因已经找到了， AppPlugin.groovy

protected void resolveReleaseDependencies() {
        // Pre-split all the jar dependencies (deep level)
        def compile = project.configurations.compile
        compile.exclude group: 'com.android.support', module: 'support-annotations
        rootSmall.preLinkJarDir.listFiles().each { file ->
            if (!file.name.endsWith('D.txt')) return
            if (file.name.startsWith(project.name)) return

            file.eachLine { line ->
                def module = line.split(':')
                compile.exclude group: module[0], module: module[1]
            }
        }
    }

求问下，为什么要将这个库单独 exclede 呢？我改为 jar 方式引用，目前没发现什么问题。@galenlin

@bovyoung 这个库是官方稳定的通用库，不需要独立更新，所以设计上是直接放在宿主或分身里（AppCompat会默认依赖这个包），插件里 exclude 掉以避免出现类重复。
