Skipping upload for missing aar and pom file

Question

I'm building an aar Library for Android and im facing an issue. POM and ARR files are not uploaded.

There is a error

Skipping upload for missing file 'F:\Android\Personal_Project\sampleMavenLib\sinalib\build\outputs\aar\sinalib-release.aar'. Skipping upload for missing file 'F:\Android\Personal_Project\sampleMavenLib\sinalib\build\publications\Production\pom-default.xml'.

I checked these two path and the aar file was there and its generated but there isnt any path for pom file

this is my gradle

apply plugin: 'com.android.library'
apply plugin: 'com.jfrog.bintray'
apply plugin: 'maven-publish'

Answer 1

After I tried a lot of things i found two points :

1 - i changed this

artifact("$buildDir/outputs/aar/sinalib-release.aar")

to

artifact("build/outputs/aar/sinalib-release.aar")

2 - The repository that you create in bintray.com should be the same as the repo in the pkg part.

this solved the Error Skipping upload for missing file and it uploaded the arr file. But One error still remains that it cant upload and generate pom file.

So i found this command:

clean build generatePomFileForProductionPublication bintrayUpload

It was working for me but still, have a problem with adding dependencies into pom although I have this code it doesn't work :

//The publication doesn't know about our dependencies, so we have to manually add them to the pom
        pom.withXml {
            def dependenciesNode = asNode().appendNode('dependencies')

            //Iterate over the compile dependencies (we don't want the test ones), adding a <dependency> node for each
            configurations.compile.allDependencies.each {
                def dependencyNode = dependenciesNode.appendNode('dependency')
                dependencyNode.appendNode('groupId', it.group)
                dependencyNode.appendNode('artifactId', it.name)
                dependencyNode.appendNode('version', it.version)
            }
