Answer 1

With Android Studio 2.3(AS) the project works fine and i can able to run the App. After updating the AS to Android Studio 3.0. i too got the error as below for libraries and build types.
Unable to resolve dependency for ':app#dexOptions/compileClasspath': Could not resolve project : library_Name.
Unable to resolve dependency for ':app#release/compileClasspath': Could not resolve project : library_Name.
To Solve the issue, simply.
What ever the
buildTypes{
debug{ ... }
release{ ... }
}
you have in your (app) build.gradle file, You have to include all the buildTypes{ } with same names as like
buildTypes{
debug{ ... }
release{ ... }
}
in to build.gradle files of All libraries/modules included in project.
clean and rebuild the project, the issue will be fixed.
Still issue not fixed, update the gradle-wrapper.properties to
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

Answer 2

As stated in the official migration guide, this error is encountered when:
Your app includes a build type that a library dependency does not
android {
buildTypes {
release {
...
}
dexOptions {
...
// release & debug is in project animators
matchingFallbacks = ['release', 'debug']
}
debug {
...
}
}
}
Correct place to find the info is now this documentation

Answer 3

Make sure you're in your project
Open the Preferences, by clicking File > Settings (on Mac,
Android Studio > Preferences).
In the left pane, click Build, Execution, Deployment >> Gradle.
Uncheck/disable the Offline work checkbox.
Click Apply or OK.

Answer 4

I spent a lot of time on this issue and none of above solutions work for me. The names and number of build types were also exactly equal in both app and library project.
The only mistake I was making was - In library project's build.gradle, I was using line
apply plugin: 'com.android.application'
While this line should be -
apply plugin: 'com.android.library'
After making this change, this error got resolved.

Answer 5

Modify all
compile project(':library:yourproject')
to
implementation project(path: ':library:yourproject', configuration:'default')
in your app build.gradle. Note the line with configuration.

Answer 6

I tried everything from unchecking offline work to matchingFallbacks. But nothing worked.
Then, in dependencies of app.gradle,
instead of
implementation project(':lib-name')
I used,
implementation project(path:':lib-name', configuration: 'default')
Eg: implementation project(path:':myService', configuration:
'default')
And it worked like a charm. :)
I was adding a dependency module with service and am not making a library as its a part of AOSP project.
Just in case, it helps someone.

Answer 7

Solution:
Dowload the ultimate version of Gradle
http://services.gradle.org/distributions/
gradle-4.x-rc-1-all.zip.sha256 09-Jan-2018 01:15 +0000 64.00B
Unzip the distribution
Go to Android Studio -> File -> Settings -> Gradle -> Use local gradle distribution
Search the file and OK
In the gradle:app write this, implementation(path: ':animators', configuration: 'default')
dependencies {
.
.
.
implementation project(path: ':animators', configuration: 'default')
}

Answer 8

Here is how I solved my problem:
instead of
compile project(':library_name')
compile project(':library_name')
in app gradle I have used
implementation project(':library_name')
implementation project(':library_name')
And in my build types for example
demoTest {
.........
}
I added this line
demoTest {
matchingFallbacks = ['debug', 'release']
}

Answer 9

I had the same issue, and solved it by adding 'mavenCentral()' to build.gradle(Project)
allprojects {
repositories {
...
mavenCentral()
}
}

Answer 10

My problem is below
Unable to resolve dependency for ':app#debug/compileClasspath': Could not download rxjava.jar (io.reactivex.rxjava2:rxjava:2.2.2)
Solved by checking Enable embedded Maven Repository

Answer 11

Even, I have faced the same issue.
I have fixed the issue by referring the above
Solution 2 with the new g‌​radle-4.1 :
I have done the following gradle changes.
It seems downloading resources through maven Amazon helped me to fix the issue, there are issues with appcompat library. Check and ensure that appcompat compatible support libraries downloaded in your system. What I feel, it just simply the resources not downloaded through maven, causing the compile error issue. Ensure the resources are found in your local drive to fix the issue.
Just Played around with
Maven Amazon url
repositories {
maven {
url "https://s3.amazonaws.com/repo.commonsware.com"
}
jcenter()
}
Compatible support libraries downloaded in the drive and referring compatible libraries in gradle.
dependencies {

implementation 'com.android.support:appcompat-v7:26.0.0-alpha1'
implementation 'com.android.support:support-v4:26.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'

Answer 12

Change this code in gradle:
compile project(':yourLibrary')
to
implementation project(path: ': yourLibrary', configuration:'default')

Answer 13

I found two type of solutions :
Solution with the old g‌​radle-3.3 :
As first and temporary solution to make the project run with android studio 3.0 , I maintain the old config of my previous of Android Studio 2.3
distributionUrl=https://services.gradle.org/distributions/g‌​radle-3.3-all.zip , compileSdkVersion 25** and **buildToolsVersion "25.0.3" and classpath 'com.android.tools.build:gradle:2.3.3
Solution with the new g‌​radle-4.1 :
To work with the new features of gradle 4.1 and the classpath com.android.tools.build:gradle:3.0.0' , I followed this link https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html . So, Those are my implementations :

In the build.gradle of the library animator I upgrade targetSdkVersion to 26 :
apply plugin: 'com.android.library'
android {
compileSdkVersion 26
buildToolsVersion '26.0.2'
defaultConfig {
minSdkVersion 21
targetSdkVersion 26
versionCode 1
versionName "1.0"
}
}
dependencies {
implementation "com.android.support:support-compat:26.0.2"
implementation "com.android.support:support-core-ui:26.0.2"
implementation "com.android.support:recyclerview-v7:26.0.2"
}

Answer 14

you just need to reset dependencies in app.gradle file
like old one as
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
to new one as
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

Answer 15

Make sure you have disabled "Offline work" in Gradle settings (Setting->Build, Execution, Deployment->Build Tools->Gradle).
I made this mistake. I followed a guide on speeding up gradle builds and had turned on the Offline work option. If that is enabled, Gradle won't be able to download any new dependencies and hence will result in the "Unable to resolve dependency" error.

Answer 16

I met the same problems and has solved.
Due to my situation, I guess your build.gradle file for app project contains snippets below:
android {
...
buildTypes {
debug {...}
release {...}
dexOptions {...}
}
}
but actually, dexOptions is not a build type, you should move dexOptions section out buildTypes, like this:
android {
...
dexOptions {
...
}
buildTypes {
debug {...}
release {...}
}
}
Hope that can help someone.

Answer 17

Adding productFlavors{} to the app build.gradle solved the issue for me. See below:
buildTypes {
release {
...
}
}
productFlavors {
}

Answer 18

This may also happen when you add a reference to the feature module that uses the incorrect plugin type. Simply change com.android.application to com.android.feature or com.android.library

Answer 19

I think it's from gradle-wrapper.properties file :
make distribution url distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
and do not upgarde to : distributionUrl=https\://services.gradle.org/distributions/gradle-4 ....

Answer 20

It seems like it's a bug on Gradle. This solves the problem for me, but it's not a solution. We have to wait for a new version fixing this problems.
On build.gradle in the project set classpath 'com.android.tools.build:gradle:2.3.3' instead classpath 'com.android.tools.build:gradle:3.0.0'.
On gradle-wrapper.properties set https://services.gradle.org/distributions/gradle-3.3-all.zip instead https://services.gradle.org/distributions/gradle-4.1.2-all.zip

Answer 21

In my case, the problem I had was due to a dependency I was trying to import (BottomNavigationViewEx).
This dependency requires to be downloaded from jitpack.io and maven.google.com, and I was putting this config in buildscript section:
buildscript {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" } // this is incorrect
maven { url "https://maven.google.com" } // this is incorrect
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
}
}
which it was incorrect, I need to remove these two maven lines and include them in the right section, 'allprojects':
allprojects {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
}
}
Hope it helps somebody as same for me.

Answer 22

I tried all the solutions given above and none of them worked for me, I ensured that I have exact build types and product flavours in my library module and app module.

Answer 23

This thread seems to have wondered a bit, however as relating to the original question, not only do you have to have your buildTypes in both build.gradle files, you need to have your productFlavors (if you are using them of course) in both build.gradle files as well.

Answer 24

I tried running Android studio 3.0.1 with internet connection. Android studio started downloading something from a link automatically which was showing in Gradle build notification. I can't say this is a sure answer but try this out.. maybe you can get your issue resolved.

Answer 25

If using Android Studio on Linux:
go to: Home/Android Studio Projects folder/App name folder
open terminal on that page and type:
./gradlew -Dhttp.proxyHost
check if JAVA_HOME is set on valid directory, if not set valid location finally rebuild your project.
NOTE: if that doesn't work remove gradle cache folder or all of that
and download again with Android Studio.

Answer 26

Add the library from File->Right click->New->Module->Import Eclipse ADT project->brows your library->finish
Now add in the app gradle setting following code:
implementation project(':library')
Finally add in the setting gradle following code:
include ':app', ':library'

Answer 27

After updating android studio to 3.3. I faced this problem when I tried to load Firebase JobDispatcher.
Adding this link on gradle.properties solved my problem
distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

Answer 28

I know none of the above solutions is gonna work as I have remained stuck into this sort of issue a long time, finally resolved this issue after watching the issue very carefully, which is pointing that
Unable to resolve dependency for ':app#dexOptions/compileClasspath':
Could not resolve project : library_Name.
You need to make a sure and double check if the class is residing there. This one thing will prove much helpful to many I guess because focusing on this point took me much closer to the solution. Now if nothing exists in that folder path you need to get the whole stuff like src folder build folder etc everything, copy that and paste it over there sync/rebuild project, if needed try invalidate and restart android studio. Hope so this will get you out of trouble as happend in my case.
Thanks
