我在同步gradle时在android Studio 2.2.3中出现以下错误.

错误:原因:无法找到所请求目标的有效证书路径

我该如何解决这个问题

我也在添加我的Gradle文件

apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "com.sample.myapplication"
    minSdkVersion 16
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
} } dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:palette-v7:23.4.0'
testCompile 'junit:junit:4.12'
// FireBase
compile 'com.google.firebase:firebase-messaging:9.0.0'
}//Add this line
apply plugin: 'com.google.gms.google-services'

和项目级别Gradle文件

buildscript {
repositories { …
