我将 Android Studio 更新到最新版本，并让它“修复项目”之类的 - 但现在我的项目无法编译，给了我

然而，仅仅通过多重索引并不能解决这个问题，因为当我添加这个时：
defaultConfig {
...
multiDexEnabled = true
}
有时候是这样的

我尝试将构建工具更改为最新版本
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
因为默认情况下它更改为20.0.0，这似乎使用了4.4W的SDK，但这并没有解决我的问题。
有谁知道这里可能出了什么问题？
EDIT:
更改构建工具或编译 SDK 并没有解决问题。
将应用程序转变为多 dex 项目并添加以下内容
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
...
multiDexEnabled true
}
...
dexOptions {
incremental true
javaMaxHeapSize "4g"
}
}
修复了构建过程，但这似乎仍然只是一种“处理”，而不是解决问题。
我不确定这是否相关，但这是我的依赖项列表：
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:appcompat-v7:21.0.2'
compile 'com.squareup:otto:1.3.5'
compile 'com.squareup.picasso:picasso:2.4.0'
compile 'com.squareup.retrofit:retrofit:1.7.1'
compile 'com.jakewharton:butterknife:6.0.0'
compile 'com.madgag.spongycastle:core:1.51.0.0'
compile 'com.madgag.spongycastle:prov:1.51.0.0'
compile 'com.madgag.spongycastle:pkix:1.51.0.0'
compile 'com.google.code.gson:gson:2.3'
compile 'commons-io:commons-io:2.4'
compile 'org.apache.httpcomponents:httpclient-android:4.3.5'
compile 'com.squareup.dagger:dagger:1.2.2'
compile 'com.squareup.dagger:dagger-compiler:1.2.2'
compile('com.googlecode.json-simple:json-simple:1.1.1') {
exclude module: 'junit'
}
compile 'com.google.android.gms:play-services:6.5.87'
}
从那时起，唯一的新依赖项是最后一行，我按照https://developer.android.com/google/gcm/client.html https://developer.android.com/google/gcm/client.html所以我认为这不是问题的根源。
EDIT2:
是的，这就是问题的根源。正如我所需要的Google Cloud Messaging，我用基础替换了该依赖项http://developer.android.com/google/play-services/setup.html#split http://developer.android.com/google/play-services/setup.html#split :
compile 'com.google.android.gms:play-services-base:6.5.87'
它解决了问题。感谢您的帮助。
EDIT3:
从 Play Services 7.0.0 开始，GCM 处于
compile 'com.google.android.gms:play-services-gcm:7.0.0'
EDIT4:
Play 服务已更新至 7.3.0。
请在此处检查最新版本：http://developer.android.com/google/play-services/setup.html#split http://developer.android.com/google/play-services/setup.html#split
