为什么gradle总是说

"所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃).找到版本27.1.1,27.1.0.示例包括 com.android.support:animated-vector-drawable:27.1.1和 com.android.support:exifinterface:27.1.0"

哪里是27.1.0 ??

build.gradle:

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
testImplementation 'junit:junit:4.12'

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'

implementation 'com.google.code.gson:gson:2.6.2'

implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.android.gms:play-services-location:15.0.1'
implementation 'com.squareup.picasso:picasso:2.71828'


implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-messaging:17.3.0'

implementation 'com.karumi:dexter:5.0.0'

}
