Unable to resolve dependency for ':app#debugUnitTest/compileClasspath', :app#debugAndroidTest/compileClasspath - gradle

Question

Situation:
Create the simplest project
Add to the project module as File -> New -> New module "Phone & Tablet Module"
Add the dependency on the module
And get errors:
Unable to resolve dependency for ':app#debug/compileClasspath': Could not resolve project :testmodule.
Unable to resolve dependency for ':app#debugAndroidTest/compileClasspath': Could not resolve project :testmodule.
Unable to resolve dependency for ':app#debugUnitTest/compileClasspath': Could not resolve project :testmodule.
Unable to resolve dependency for ':app#release/compileClasspath': Could not resolve project :testmodule.
Unable to resolve dependency for ':app#releaseUnitTest/compileClasspath': Could not resolve project :testmodule.
Below are the project files:
Project:

repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

google()
jcenter()

include ':app', ':testmodule'
Note:
If the module type is "Android Library" (Point "two" above), then there are no such errors.
For such a simple project, where everything is by default, there should not be such errors. What's wrong?

Answer 1

Try this, replace:
implementation project(':testmodule')
To:
implementation project(path:':testmodule', configuration: 'default')

Answer 2

Go to
File -> Settings -> Build, Execution, Deployment -> Gradle menu.
You will see "Offline work" options. Uncheck it. And it's ok.

Answer 3

It looks like your plugin needs to be changed to apply plugin: 'com.android.library' instead of 'com.android.application'
See this post for more
information. Hope that helps.

Answer 4

Try online mode for gradle. Hope it helps(I had the same problem, so more chances).
