key store存在，忘记了 keystore pwd， ke

my spec:

gradle version: 4.6
Android Studio 3.2
Build #AI-181.5540.7.32.5014246, built on September 18, 2018
JRE: 1.8.0_152-release-1136-b06 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 4.15.0-42-generic

solution:
找到当前项目(project)下的.gradle/4.6/taskHistory.bin，双击以text文本强行打开，Ctrl+F搜索signingConfig.storePassword和signingConfig.keyAlias。根据，我刚刚的经验，对应的密码应该会在Ctrl+F之后，靠后的几条结果。请立即保存，争取别犯这种错了。

搜索结果示例(fake alias&&pwd):
signingConfig.keyAlias��WechatQQ�signingConfig.keyPassword��12WeQQchat12�signingConfig.storePassword��12WeQQchat12�
