今天在项目中遇到了一个很奇葩的问题，
Android dependency 'com.android.support:support-support-v4' has different version for the compile (23.2.0) and runtime (27.0.2) classpath. You should manually set the same version via DependencyResolution.
很明显这是我们导入了两个不同版本的jar导致的，因此我们要想办法解决，找了一下，经过自己的理解，只需要在根项目的build.gradle中配置如下配置：
impletation("com.android.support:27.0.2") {
exclude group: 'com.android.support', module: 'support-compat'
}
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support:appcompat-v7'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "27.0.2"
}
}
}
}
然后重新build一下即可，
