Javapoet not found in processor

I created an Android library that uses JavaPoet to generate classes. It works well on my local workspace ; even if I include the library module into another project.
Now I'm trying to put my project online through bintray. The project is uploaded correctly, but then when I include it in a new project and build the projet I get this message :
Error:Bad service configuration file, or exception thrown while
constructing Processor object: javax.annotation.processing.Processor:
Provider me.aflak.filter_processor.FilterProcessor could not be
instantiated: java.lang.NoClassDefFoundError:
com/squareup/javapoet/TypeName
I guess it comes from the way I manage the dependencies... Compiletime, Runtime stuff...
This is processor build.gradle :
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation project(':filter-annotation')
api 'com.squareup:javapoet:1.9.0'
compile 'com.google.code.gson:gson:2.8.1'
compile 'com.google.auto.service:auto-service:1.0-rc3'
}
This is annotation buid.gradle :
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.8.1'
}
This is how I include the library in an empty project :
// build.gradle project
repositories {
maven{
url 'https://dl.bintray.com/omaflak/maven'
}
}
// build.gradle module
dependencies {
compile 'me.aflak.libraries:filter-annotation:1.0'
annotationProcessor 'me.aflak.libraries:filter-processor:1.0'
}
Could someone point me out to the right direction ? Thanks !

I finally got the solution (a bit randomly though :p).
I had to add mavenLocal() in the library module.

android unresolved dependencies error when creating a new project

I have updated my Android studio, but after that, I cannot create a new project. My Android version is 2.2 beta 3.
This is an image of the error messages when attempting to create a Gradle sync project:

I was having the same problem, but I have fixed mine by removing this line of code from my Gradle module (app) level:
After removing to sync the project hopefully it will fix the problem.

Edit the dependencies in gradle app as:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:24.2.1'
}
This worked for me :)

1.go to settings
2.select gradle option.
3.uncheck "offline work".
4.rebuild project.
5.that's it. make sure you have a internet connection.

Try adding the dependencies repositories in Project build.gradle
allprojects {
repositories {
google()
jcenter()
"Your dependencies repositorie"
}
}

Is commenting junit test in Android Studio a safe way?

I recently migrated from Eclipse to Android Studio and I'm using Android Studio 1.5.1. Before when I started Android Studio, I got this error:
Failed to resolve: junit:junit:4.12
After searching in Google and trying some proposed options, only commenting junit test in app/build.gradle solved the problem:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
// testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:design:23.0.0'
}
But I want to know is this a good and safe option to resolve that problem? For example does it cause any problem in future?

You will need to add the following to your build.gradle file and it should work fine.
repositories {
maven { url 'http://repo1.maven.org/maven2' }
}

gradle project sync failed android studio

I'm trying to setup nhaarman/ListViewAnimations inside of Android Studio 1.1.0.
From Setup:
Add the following to your build.gradle:
repositories {
mavenCentral()
}
dependencies {
compile 'com.nhaarman.listviewanimations:lib-core:3.1.0#aar'
compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0#aar'
compile 'com.nhaarman.listviewanimations:lib-core-slh:3.1.0#aar'
}
yet Android Studio says:
Gradle project sync failed. Basic functionality (e.g. editing,
debugging) will not work properly.
Error:(26, 0) Gradle DSL method not found: 'compile()'
Possible causes:<ul><li>The project 'X' may be using a version of Gradle that does not contain the method.
Gradle settings</li><li>The build file may be missing a Gradle plugin.
Apply Gradle plugin</li>

You are adding these dependencies in the top level build.gradle file.
You have to add these lines in the module build.gradle file.
root
build.gradle //top level
app
build.gradle //module level

After adding those lines to:
build.gradle (Module: app)
instead of
build.gradle (Project: app)
the error is gone.

Try this:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.nhaarman.listviewanimations:lib-core:3.1.0'
compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0'
}

Try removing #arr. worked for me.
//ListView Animations
compile 'com.nhaarman.listviewanimations:lib-core:3.1.0'
compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0'

Android Studio - MavenCentral dependency sync ok, but symbol cannot be resolved

So, I managed to create an Android library component and publish it on Maven Central. But when I'm trying to use it as a dependency in a new project, Android Studio can't seem to find the classes.
build.gradle for the app module:
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0' //this is the one I want to use
}
This part seems to work, at least I get no sync errors. However, when trying to access to package and classes from my MainActivity, Android Studio can't find them and gives me "cannot resolve symbol" message.
I have tried downloading the classes.jar from the archive directly from Maven Central, and they are indeed in the package.
Other dependencies seem to appear in the /build/intermediates/exploded-aar folder after syncing, but that does not happen to my library.
I use Android Studio 1.0.2 on OSX 10.9.5 (Mavericks)
Any suggestions?

Looking in your pom, it states <packaging>aar.asc</packaging>. It should be aar instead.

Oh, and the answer to actually being able to use the library, was to add #aar to the dependency so that it now reads
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0#aar' //note the magic #aar
}
Edit:
Removing the block
configurations {
archives {
extendsFrom configurations.default
}
}
makes Gradle generate the pom with the correct packaging entry, and thus makes it possible to reference the dependency without the #aar suffix
