3.问题原因

3.1. 原因

D:\AndroidStudioProject\lava_packages_apps_PowerSave>gradle compile DebugJavaWithJavac
Observed package id 'platforms;android-lava6737-503' in inconsistent location 'D:\AndroidStudioProjectsSDK\sdk\platforms\android-lava6737-503-203' (Expected 'D:\AndroidStudioProjectsSDK\sdk\platforms\android-lava6737-503')
Incremental java compilation is an incubating feature.            
1

根据提示将 android-lava6737-503-203

D:\AndroidStudioProjectsSDK\sdk\platforms\android-lava6737-503-203

修改为

D:\AndroidStudioProjectsSDK\sdk\platforms\android-lava6737-503

3.2. Could not find tools.jar

* What went wrong:
Execution failed for task ':compileReleaseJavaWithJavac'.
> Could not find tools.jar

查看环境变量和查看Java的文件位置，发现最近Java自动更新了版本，导致编译不过

C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;D:\Eclipse\sdk\platform-tools;D:\MySQL\bin;D:\GitSoftware\Git\bin;D:\Python36\Scripts;D:\Android_Studio\StudioSoftWare\gradle\gradle-2.10\bin;D:\Go\bin;C:\MinGW\bin;
1

新增java环境变量

C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;D:\Eclipse\sdk\platform-tools;D:\MySQL\bin;D:\GitSoftware\Git\bin;D:\Python36\Scripts;D:\Android_Studio\StudioSoftWare\gradle\gradle-2.10\bin;D:\Go\bin;C:\MinGW\bin;C:\Program Files\Java\jre1.8.0_171\bin;C:\Program Files\Java\jdk1.8.0_131\bin;
1

找到当前用户目录下的 .gradle 目录，若不存在则创建 gradle.properties 文件，然后在文件中输入如下内容：

org.gradle.java.home=C:\\Program Files\\Java\\jdk1.8.0_131
1

然后重启gradle，执行 gradle aR
