I just build successfully!!
I reinstall java8 and set the path by running this command export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home again. As a result, I did it:sob::sob:

Sorry for bothering you...

If I have time and a chance to contribute your app, I will try it!

Thanks a lot:sob::sob:

Can you check JDK version?
java -version
🙏

takahirom on 4 Feb 2020

Thanks for swift reply! Run the command java -version in the terminal and the result is as follows.

openjdk version "13.0.2" 2020-01-14
OpenJDK Runtime Environment (build 13.0.2+8)
OpenJDK 64-Bit Server VM (build 13.0.2+8, mixed mode, sharing)

KaoruMuta on 4 Feb 2020

If you Android Studio installed. Please this
export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home
Or please install JDK 8 and use that JAVA_HOME

takahirom on 4 Feb 2020

I've already installed Android Studio 3.5.1.
I try to run the command export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home. But I still failed to build.

In addition, I try to install JDK8 brew cask install adoptopenjdk8 and set Java8 by running this command export JAVA_HOME=$(/usr/libexec/java_home -v 1.8). But I still failed.

KaoruMuta on 4 Feb 2020

Can you run this?
./gradlew :android-base:assembleDebug
If this success, Xcode can not look JAVA_HOME

takahirom on 4 Feb 2020

I tried this, and the result is as follows. (not successfully..)

Please tell me stacktrace 🙏
./gradlew :android-base:assembleDebug --stacktrace

takahirom on 4 Feb 2020

Sure.
I'm just starting job from now, so after this, I will tell you stacktrace.

Regards.

KaoruMuta on 4 Feb 2020

@KaoruMuta
Can you try this with Android Studio 3.6?

ry-itto on 4 Feb 2020

@takahirom @ry-itto
Sorry for late reply.
I uninstalled Android Studio 3.5.1, and just try to install Android Studio 3.6 RC 2, and run the command ./gradlew :android-base:assembleDebug --stacktrace on the directory named conference-app-2020.

Finally, the results are as follows. Is there something wrong with gradle version?
Regards.

Welcome to Gradle 6.1!

Here are the highlights of this release:
 - Dependency cache is relocatable
 - Configurable compilation order between Groovy, Java & Scala
 - New sample projects in Gradle's documentation

For more details see https://docs.gradle.org/6.1/release-notes.html

Can you add this to local.properties?

sdk.dir=/Users/[your user name]/Library/Android/sdk

Thanks for swift reply!
I just checked local.properties, and it seems that the script sdk.dir=/Users/k_muta/Library/Android/sdk had already been written..

(k_muta is my user name)

@KaoruMuta Hi 😄
Could you please try Invalidate caches / Restart and remove .gradle dir ?

In case someone else encounters the same problem (for any Android project)..

For me the cause was that ANDROID_HOME environment variable was not set, nor did the local.properties file contain value for key sdk.dir.

Setting either of these variables to point to the where the Android SDK is installed - fixes the issue.

This issue appears when the project has data binding enabled and even for Gradle tasks that don't use the Android SDK for anything.

So, for example, if you want to execute such a Gradle task on an environment that doesn't have any Android SDK installed - you can set ANDROID_HOME to any path (eg: ANDROID_HOME=/tmp) and it will work (provided that the task you'll be running doesn't require Android SDK)
