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.

com.mcruiseon.buseeta E/dalvikvm: Unable to resolve Lmy/library/class/file; annotation class 8906

My library project starts like this
#XmlRootElement(name = "GetUserDomainOrGroupMasterResponse")
#XmlAccessorType(XmlAccessType.FIELD)
public class GetUserDomainOrGroupMasterResponse implements Serializable,
I have built a jar, and copied this jar to the libs folder of my android project using android studio.
My gradle file in my android studio project has
compile fileTree(dir: 'libs', include: ['*.jar'])
I also tried adding
compile files('libs/mylibrary.jar')
When I open the jar archive the class file is RIGHT THERE
Now, when I run my project I get a
com.myapp.package E/dalvikvm: Unable to resolve Lmy/library/class/file; annotation class 8906
I have tried
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/mylibrary.jar')
compile files('libs/mylibrary.jar')
3.
compile fileTree(dir: 'libs', include: ['*.jar'])
I have also tried building a executable jar for my jar file and still I get the damn Error
I dont get it. What am I missing here ?
Edit
I noticed that the app does not have any side effect due to this Error. In any case its a irritant. Please help me resolve this.

#XmlRootElement annotation has retention RUNTIME in jaxb-api. This annotation should be available in runtime as normal classes (https://en.wikipedia.org/wiki/Java_annotation).
Since your library compiled against jaxb it has a notion of this annotation, but it is not included and can not be found in runtime.
As a solution, you could add jaxb as compile dependency to your app (several Mb plus) or add just this annotation definition to your android project.

How to avoid use dependencies again (Android)?

I've created an Android library with Studio and this library needs some 3rd libraries. The build.gradle looks like below:
dependencies {
compile fileTree(dir: 'libs', include: ['*.*'])
compile 'some library:1.3.2'
compile 'some other library:1.3.4'
}
The library can be compiled freely and finely, and then I push them in to local Maven. Everything fine!
Now I create a client application just for a sample of my library. What confusion is that I must do follow:
dependencies {
compile fileTree(dir: 'libs', include: ['*.*'])
compile 'mylibrary:1.0'
compile 'some library:1.3.2'
compile 'some other library:1.3.4'
}
Which means to include the two 3rd libraries. Otherwise I must get errors "NoClassFound" which relevant to the two libraries.
You know the
compile 'mylibrary:1.0'
is the meaning to include my library, but why should I include the other twos which were used by "mylibrary"? Could I avoid that and just -compile 'mylibrary:1.0' ?

OK, I've solved project with the help of #CommonsWare

Android Studio with Gradle incompatibility (Google Play Services issue)

I am developing an android app with Android Studio 0.8.9. I am using Gradle to build my project.
I want to include google-play-services.jar file into my project in order to use push notification api.
I have added those statements into my gradle (application layer) file as follows:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/google-play-services.jar')
compile files('libs/android-support-v4.jar')
compile files('libs/gson-2.2.3.jar')
compile files('libs/volley_23042014.jar')
compile 'com.google.android.gms:play-services:5.2.08'
}
but it never works. I get the following error:
Multiple dex files define Lcom/google/ads/AdRequest$ErrorCode;
I've checked bunch of websites (including Stackoverflow.com). None of them has worked for me.
I have latest versions of Google Support Library, Google Support Repository, Google Play Services.
Here is my libs directory
My SDK version like:
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="20" />
What I have done wrong? If anyone has any idea please let me know.

If you're including Play Services via:
compile 'com.google.android.gms:play-services:5.2.08'
you don't need this:
compile files('libs/google-play-services.jar')
so just remove it.
Since the first line of your dependencies will make it automatically pick up any jar files you put in your libs directory:
compile fileTree(dir: 'libs', include: ['*.jar'])
make sure you remove the jars from there as well.
For that matter, there are other libraries you shouldn't include via specific jars.
Instead of this:
compile files('libs/android-support-v4.jar')
compile files('libs/gson-2.2.3.jar')
use this:
compile 'com.android.support:support-v4:20.0.0'
compile 'com.google.code.gson:gson:2.2.3
(Note that later versions of GSON are available).

error: package com.facebook.android does not exist in android studio project

I am new to android studio.I am developing an app which uses Facebook SDK.I have downloaded Facebbok SDK and imported it as a module to my android project.I am using latest version of android studio.So I simply imported it and did not make any change in other files for this.First I am trying to use facebook login functionality.But when I build the app I am getting following error.
error: package com.facebook.android does not exist
I could see one solution as an answer to someone's question. But i could not understand it.Please somebody help me.

check you build.gradle
it should got this dependency
if you got library project:
dependencies {
compile project(':facebook');
}
if you got jar files in libs folder:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
}
or just add maven central dependency to:
dependencies {
compile 'com.github.asne.facebook:facebook:3.17.2'
}

You need to add dependencies on your gradle file :-
compile 'com.facebook.android:facebook-android-sdk:4.1.0'
above is path you need to add dependencies {} like below :-
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.facebook.android:facebook-android-sdk:4.1.0'
}

Is the facebook library is jar file or library project?
If is jar file, you just need to add jar file in libs folder and dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
} in build.gradle.
If is library project, you should modify your setting.gradle and build.gradle files.

Adding this line of code to the dependencies in the build.gradle file helped me get rid of the same error.
dependencies {
...
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}
From platform=android facebook developers
-the last line of the section "Add Facebook SDK to Your Project")
