升级Android Studio3.0时遇到的几个问题

1.gradle打包，自定义apk名称代码报错（Cannot set the value of read-only property 'outputFile' ）

报错

Error:(56, 0) Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
Open File​

解决 ：修改文件名代码请这样写

android.applicationVariants.all { variant ->
        variant.outputs.all {
          outputFileName = "xm_${config.versionName}_${releaseTime()}.apk"
        }
      }

2. AAPT2 编译报错 AAPT2 error

报错

Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

解决：在gradle.properties中关闭APPT2 编译

android.enableAapt2=false

注：如果是eclipse转到as上的项目，可能没有gradle.properties文件，请在项目根目录中手动创建

3.apt插件问题（Error:Cannot choose between the following configurations of project :mylibrary:）

报错:

Error:Cannot choose between the following configurations of project :mylibrary:

- debugApiElements
- debugRuntimeElements
- releaseApiElements
- releaseRuntimeElements
  All of them match the consumer attributes:

解决

//1.在project的build.gradle中删除
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
//2.在module的build.gradle中删除
apply plugin: 'android-apt'
//3.将module的build.gradle文件中的dependency
apt 'com.jakewharton:butterknife-compiler:8.1.0'
//改为
annotationProcessor 'com.jakewharton:butterknife-compiler:8.1.0'

其他使用apt的依赖，也要这样更改

4.Android Studio3.0 preview已知bug(Error:Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error)

报错:

Error:Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error include:


Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

解决:

1. 尝试升级kotlin版本，不过该问题可能存在于preview版本中

//在build.gradle文件中将kotlin版本从
ext.kotlin_version = '1.1.2-3'
//改为
ext.kotlin_version = '1.1.2-4'

2.尝试降低Butterknife的版本

//将Butterknife的版本降级为8.4.0
compile 'com.jakewharton:butterknife:8.4.0'
