I trying to assemble my project, but I only get an error:
Error:Execution failed for task ':basetools:processDebugAndroidTestResources'.
> No slave process to process jobs, aborting
I didn't change anything in my gradle files but abruptly got this error.
I already tried invalidate cahces and restart, rebuild
What should I do to fix it?

Go to Android Studio, click "File" and click "Invalidate Caches / Restart...". This will work.
change
minifyEnabled true
to
minifyEnabled false
if above changes does not work then try this as well
shrinkResources true
to
shrinkResources false
Restarting Android Studio wasn't enough to resolve this error for me: I also had to kill an aapt2 process which had been left behind.
Same issue. Invalidate caches and restart done the job for me.
You can delete build folder in project and modules. After Invalidate Caches and Restart , it work for me!
You can try it
'Clean Project'、'rebuild project' doesn't work.I solved this problem by invalidate and restart
Delete build folder manually (project's build and modules' build)
Delete old .impl file
Restart Android Studio
I was going through some RnD and applied above nothing worked, rather that made my project to crash completely and re do.
I was not shutting down and restart the system everyday.
When I got the next time I simply didn't do anything but restarted the system. It worked fine!!..
Guys , keep in mind : Invalidate Caches and Restart will make you loose complete history of code changes.
shrinkResources to false /
minifyEnabled to false will cost you few kbs of apk size

Unable to merge dex
You have a dependencies conflict. Try to see your dependencies via command ./gradlew app:dependencies (Details here ). And you will see the next situation:
As you can see android-mail depends on android-activation. I think you don't need to use the line implementation 'com.sun.mail:android-activation:1.6.1'
P.S. For debugging builds you can use the next flag "--stacktrace". Then you can see more information about your issue.
I'm beginner with android and gradle. I saw this error so I removed the hamcrest dependency from my module gradle but I still see the following error:
Error:Execution failed for task ':app:preDebugAndroidTestBuild'.
Conflict with dependency 'org.hamcrest:hamcrest-core' in project ':app'. Resolved versions for app (1.1) and test app (1.3)
differ.
This dependency is causing the problem:

But I get the same error.
I also saw this solution but I don't know where to add the configurations exactly:
Robolectric 3.0-rc2 Hamcrest-core conflict
And I don't see why I need to have this problem if I don't use hamcrest anyway.
Thanks!

You're mixing two kinds of syntaxes. Use either
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath "gradle.plugin.me.tatarka:gradle-retrolambda:3.3.0"
}
}
apply plugin: 'me.tatarka.retrolambda'
or
plugins {
id "me.tatarka.retrolambda" version "3.3.0"
}
(gradle-retrolambda README), see also the gradle documentation.
I have the same issue.
You'll need to update a few things:
android/build.gradle:
i) classpath 'com.google.gms:google-services:4.0.1'
ii) Make sure google() appears above jcenter() in both buildscripts and allprojects
android/app/build.gradle:
Update Android libs to the latest specified here:
https://firebase.google.com/support/release-notes/android#20180523
if you have other libraries (for me, it's firebase) make sure to check build.gradle of the libraries, too.
I have the follow app bulild.gradle for my project. When I run the command gradle check no output is reported in the app/build/ folder. I basically used the same code for a previous project and it seemed to work just fine.

Check out gradle fury's quality plugin, works on android and non android projects https://github.com/gradle-fury/gradle-fury. We use it has something to force reports for the site plugin. It's largely based off of work of others with lots of tweaks to make it work correctly for both android and non android projects.
apply it
allprojects {
apply from: "https://raw.githubusercontent.com/gradle-fury/gradle-fury/master/gradle/quality.gradle"
}
and then you'll need the contents from here: https://github.com/gradle-fury/gradle-fury/tree/master/config cloned into your repo. Just the config folder, the rest of the stuff isn't needed.
finally, either call any gradle tasks that requires check. So any one of the following should do the trick
gradlew build
gradlew check
gradlew install (if you're running the maven-support stuff from fury)
Add below configuration to you gradle.build file. Basically it does not find android repository and related details in your configuration.

How to fix or diagnose this?
You should remove compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" from your dependencies section and move it to buildscript { dependencies { ... } }.
You did put compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" in the wrong build.gradle file
You may use kotlin plugin's build-in converters to deal with this. According to Kotlin Docs:
Configuring Kotlin in the project
When adding a new Kotlin file, IntelliJ IDEA (and Android Studio)
automatically prompts us as to whether we'd like to configure the
Kotlin runtime for the project. However, currently, converting
existing Java file does not prompt this action. Therefore we have to
invoke it manually (via Find Action):
We are then prompted for the version of Kotlin. Choose the latest
available from the list of installed versions.
After we configure Kotlin, build.gradle file for the application
should be updated. Now we can see that apply plugin: 'kotlin-android'
and the dependencies were added.
(For more details how to set up gradle for your project, please check
Using Gradle)
The last thing to do is to sync the project. We can press Sync Now
in a prompt or invoke an action Sync Project with Gradle Files.
From: https://kotlinlang.org/docs/tutorials/kotlin-android.html
Check link above for more information.
Hope it will help.
you need to apply only one plugin, in your case apply plugin: 'kotlin-android-extensions' and only compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" this dependency. it worked for me
