I have a problem compiling the 8th wall xr unity demo project on android. (Source: https://console.8thwall.com/quick-start) I tried different JDKs, Android Toolsets, Changed the JAVA_HOME environment path, nothing seems to work.

That's the error log I keep getting:

CommandInvokationFailure: Gradle build failed. C:\Program Files\Java\jdk1.8.0_144\bin\java.exe -classpath "C:\Program Files\Unity2017_3\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-4.0.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleDebug"

Unity Version: 2017.3.1f1

I tried the "internal" build as well, not working either.

Does anyone have an idea where the problem may be coming from, or what else i could try ?

Best wishes, Chris

Looks like your package name for the project is "com.private.xrTest". private is a keyword in Java, so you get the compiler error stating that an identifier is expected after private.

Changing your package name should resolve the compiler error.
