When I connect the new library robovm-rt, gradle swears that I already have several such classes in another library:
Duplicate class org.apache.commons.logging.Log found in modules robovm-rt-2.3.5 (com.mobidevelop.robovm:robovm-rt:2.3.5) and spring-jcl-5.1.2.RELEASE (org.springframework:spring-jcl:5.1.2.RELEASE)
Duplicate class org.apache.commons.logging.LogFactory found in modules robovm-rt-2.3.5 (com.mobidevelop.robovm:robovm-rt:2.3.5) and spring-jcl-5.1.2.RELEASE (org.springframework:spring-jcl:5.1.2.RELEASE)
Duplicate class org.apache.commons.logging.LogFactory$1 found in modules robovm-rt-2.3.5 (com.mobidevelop.robovm:robovm-rt:2.3.5) and spring-jcl-5.1.2.RELEASE (org.springframework:spring-jcl:5.1.2.RELEASE)
Duplicate class org.apache.commons.logging.impl.NoOpLog found in modules robovm-rt-2.3.5 (com.mobidevelop.robovm:robovm-rt:2.3.5) and spring-jcl-5.1.2.RELEASE (org.springframework:spring-jcl:5.1.2.RELEASE)
Duplicate class org.apache.commons.logging.impl.SimpleLog found in modules robovm-rt-2.3.5 (com.mobidevelop.robovm:robovm-rt:2.3.5) and spring-jcl-5.1.2.RELEASE (org.springframework:spring-jcl:5.1.2.RELEASE)
I tried to exclude these Apache classes from library in different ways, but none of them work, the problem remains. Not working options:
Option 1:
implementation (group: 'com.mobidevelop.robovm', name: 'robovm-rt', version: '2.3.5') {
exclude group: 'commons-logging', module: 'commons-logging'
}
Option 2:
implementation (group: 'com.mobidevelop.robovm', name: 'robovm-rt', version: '2.3.5') {
exclude group: 'org.apache.commons', module: 'commons-logging'
}
What is the correct way to exclude these classes so that they are not duplicated?
Answering my question, I just excluded the module not from the first library, but from the second one - spring-boot-starter-websocket
implementation('org.springframework.boot:spring-boot-starter-websocket') {
exclude group: 'org.springframework', module: 'spring-jcl'
}
I am developing a news app but I am getting following errors in from gradle console

You can add below 2 lines into your gradle.properties file:
android.useAndroidX=true
android.enableJetifier=true
Note to check, to not repeat any line that already exists (and ensure existing are true).
Details:
If you want to use androidx-namespaced libraries in a new project, you need to set the compile SDK to Android 9.0 (API level 28) or higher but below "API level 31", and set both of the mentioned Android Gradle plugin flags to true.
android.useAndroidX: When this flag is set to true, the Android plugin uses the appropriate AndroidX library instead of a Support Library. The flag is false by default if it is not specified.
android.enableJetifier: When this flag is set to true, the Android plugin automatically migrates existing third-party libraries to use AndroidX dependencies by rewriting their binaries. The flag is false by default if it is not specified.
Adding these lines to gradle.properties file solves "Duplicate Class" errors:
android.useAndroidX=true
android.enableJetifier=true
However, this generated new errors in my project:
"package android.support.annotation does not exist"
"cannot find symbol class Fragment"
"package android.support.v4.content does not exist"
"Program type already present"
etc.
However, the refactoring worked for me:
Migrate your project to AndroidX by selecting Refactor >
"Migrate to AndroidX" from the menu bar.
Select Build > Clean project
Restore Android Studio
Now, my project (Match4app) works with AndroidX and I was able to publish it in the PlayStore without any issues.
Comment: This task also allowed me to upgrade all other libraries that depend on AndroidX (i.e. com.firebaseui:firebase-ui-auth:6.0.2, com.google.android.gms:play-services-games:18.0.1, com.google.android.gms:play-services-auth:17.0.0, com.google.android.gms:play-services-ads:18.2.0, etc.).
I run into something like this, and below is based on my other answer:
Your project (or one of its sub-projects) is referring to a dependency using the + plus-sign at its end, like com.google.firebase:firebase-auth:+, which means, use any higher version when possible, and that newer version is no longer using android.support libraries and instead is using androidx; to fix this issue follow the below steps.
Steps:
Ensure the ANDROID_HOME environment-variable is set, and then, open a console window (like git-bash, because it keeps the whole command output), and cd into your project's android directory (for Ionic projects it should be platforms/android).
First, List all dependencies by running below (in git-bash):
./gradlew :app:dependencies
Copy the result into your preferred text-editor, and search for androidx.
If you found something follow below steps, else you are done! (and you do not need to repeat these steps).
Scroll up until you see -> at the end of any line, like for example 16.0.8 -> 19.0.0 or + -> 19.0.0, which both mean that the version was auto-resolved (to something higher than specified by you because of +).
So, set the version down manually:
When possible, in your project (or sub-project) find and replace the + sign with a specific version.
Or, force a specific version of the dependencies like mentioned below (after copying dependency id, which you found in previous-step, of course).
At last, repeat above steps (but instead of step one just clear the console).
To Force specific version of the dependencies add to your root build.gradle file something like below (which is what worked for me) but of course edit below and add your own rules (because these might not work for your case):
allprojects {
// ...
configurations.all {
resolutionStrategy {
force 'com.google.firebase:firebase-common:17.0.0'
force 'com.google.android.gms:play-services-basement:16.2.0'
force 'com.google.firebase:firebase-iid:16.0.0'
force 'com.google.firebase:firebase-auth:17.0.0'
}
}
}
I was having this same issue and this is how i resolved it
Expand Graddle Scripts and then Go to graddle.properties and add these 2 lines
Note: Maybe the first line android.useAndroidX=true is already there so do not repeat it.
android.useAndroidX=true
android.enableJetifier=true
Just set your Gradle properties this way
Just add these 2 lines in gradle.properties file,
android.useAndroidX=true
android.enableJetifier=true
Now your project will not have any duplicate class error and will work fine,
Thank you
Taken from here. AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.
Like #Ahmed says, the solution is to implement AndroidX, it works for me. However, it isn´t an easy way and it requires a bit of pacience... These are the steps that I did:
First, is very important that you do all this changes in a different branch or you make a backup of your project.
You need to have the Android Gradle Plugin Version 3.5.1. So, in build.gradle set: dependencies {
classpath 'com.android.tools.build:gradle:3.5.1'
...
Migrate to AndroidX using Android Studio Tool : Refactor --> Migrate to AndroidX...
When it finishes, it has done all pertinents modification, but posibly you can´t deploy the project correctly because you find any errors. These are the problems that I found and the solutions:
If you use Kotlin, in build.gradle set: buildscript {
ext.kotlin_version = '1.3.10'
...
and compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
If you use destination method, add "file" parameter: destination file("$reportsDir/checkstyle/checkstyle.xml")
If you use Butterknife, use 10.0.0 version
I was having this same issue and this is how i resolved it
android.enableJetifier=true
Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 28
multiDexEnabled true
}
...
}
dependencies {
implementation "androidx.multidex:multidex:2.0.1"
}
Top-Master's answer only work if you can downgrade to a specific version. In my case, I have a React Native app and one of the libraries I was using had migrated to AndroidX. The previous version had issues with iOS, so I had to use the most recent version. What I had to do was:
Migrate the Android project to AndroidX (Refactor > Migrate to AndroidX).
Use jetify to convert node_module dependencies to AndroidX. For React Native 0.60 and above, jetify is run automatically, so you don't have to install this library.
android.nonTransitiveRClass=true
add this on gradle properties
I'm using vs 2017 and xamarin.forms.
I'm getting the error "java.exe exited with 1" in the release mode with ProGuard turned on. (in the debug & without proguard its doing fine) It's a common question, i know , but i've tried all the variants and it still doesnt work.
1.tried to update proguard to 5.3 version manualy
2.to update jdk 8, to install either x64 or x86 or both
3.to change the java memory to 1g , 4g, 500 m
4.to turn on multi-desk
to edit the proguard-android.txt by adding
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
(These just ignore proguard, google play doesnt accept it.)
ANY OTHER VARIANTS HERE?

I am getting the following error:
Caused by: java.io.FileNotFoundException: class path resource [request-
ws/src/main/resources/application.yml] cannot be opened because it does
not exist
Class with the issue:
#Configuration
#PropertySource("classpath:request-ws/src/main/resources/application.yml")
public class RequestDataSource {
Now I am trying to access the yml file in from a different module. The module name is request-ws. The goal to to create two data sources. Any advice would be greatly appreciated.
The classpath for application.yml should be under: src/main/resources
according to: classpath:request-ws/src/main/resources/application.yml
you obviously don't have that yml file under:
src/main/resources/request-ws/src/main/resources/application.yml
Try to create your custom folder under: src/main/resources
Since my project is broken down into modules when the war file is made my application.yml file ends up in WEB-INF Put this on on your class:
#Configuration
#EnableConfigurationProperties
#PropertySource("classpath:WEB-INF/classes/application.yml")
public class DataSourceConfig {
I built with parse 1.5.1 without problems when progurad only add one line.
-keep class com.parse.** { *; }
I upgraded parse to 1.9.4 ,but parse didn't work.
I reference others topics and I added below lines still didn't work.
I can ignore the parse warning,but it can't solve any problems.
-keepattributes Annotation,SourceFile,LineNumberTable
-keepattributes Signature
-keep interface com.parse.** { *; }
-keep class com.parse.** { *; }
-keep class com.squareup.** { *; }
-keep interface com.squareup.** { *; }
I got error when I built the release version with Parse 1.9.4.
