Unity5.5.6 升级到 2018.4.1 打包出现的问题 : Gradle version 2.10 is required. Current version is 5.1.1
起因:最近要在googleplay上架新游戏,而谷歌要求新上架的应用要支持64位,鉴于老版本的unity不支持打包64位apk,所以决定升级unity版本到2018.4.1,
但打包过程中出现了几个问题 ->
问题1
Gradle version 配置错误,报错信息如下:
CommandInvokationFailure: Gradle build failed.
D:\Program Files\unity2018.4.17\Unity\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\OpenJDK\Windows\bin\java.exe -classpath "D:\Program Files\unity2018.4.17\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"
stderr[

由信息可知:
当前Unity2018.4.1 中的Gradle version 是 5.1.1 而我的打包要求却是2.10,如此定位应该是配置不一致问题,查之果然:
因为我在unity 5.5.6也是用gradle方式打包,新游戏延用了旧游戏的部分配置,所以mainTemplate也被拷贝了过来,如图:
查看Unity2018.4.1安装目录下的mainTemplate中的配置,路径:unity2018.4.17安装目录\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\GradleTemplates\mainTemplate.gradle,如图:
如此,解决的办法就是把unity2018.4.17安装目录\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\GradleTemplates\mainTemplate.gradle文件拷贝到Unity/Assets/Plugins/Android路径下替换旧配置,
由此,问题1解决
问题2
安卓打包方法超过64k的问题,这个还是在mainTemplate.gradle配置中调整,加上multiDexEnabled true属性即可,如图:
由此,问题2解决
最后,64位apk打包成功
