echo '将构建结束后的apk文件移动到/home/jenkins/apks目录下'
echo '获取build.gradle的versionName字段'
versionName=$(cat app/build.gradle |grep versionName | awk '{print $2}')
length=${#versionName}
aaa=`expr ${length} - 2`
name=${versionName: 1: ${aaa}}
echo ${name}
LAST_APK_NAME=$(date +%Y%m%d%H%M%S)
mv app/build/outputs/apk/*/*.apk /home/jenkins/apks/$name-$LAST_APK_NAME.apk
