i saw several posts regarding this error involving the’new’ maven-publish plugin we use instead of the old ‘maven’ plugin and for android the extra plugin to generate the pom file.
everything worked fine until i decided i need to put my versionCode and versionName inside a properties file and i gradle is activated with ./gradlew -PincreaseVersion bintrayUpload i incease the version in the property file, i do that BEFORE evaluation since i’m using getVersionName() and getVersionCode() methods inside the ‘android’ block.
moving the maven-publish ‘apply plugin’ to right before the publication {} clause OR changing publication to publication.publishing {} will work but will cause NullPointerException in the sample app project that is built as part of the project (firebase-jobdispatcher-android)
my lib gradle file looks like this:
apply plugin: 'maven-publish'
apply plugin: 'com.jfrog.bintray'
apply plugin: 'com.android.library'
//apply from: 'coverage.gradle'
//Properties versionProperties = readVersionProperties()
//updateProperties(versionProperties)

this file works! but i i try to remove the comment from getVersionName() and getVersionCode() i get either NullPointerException OR the error that is in the title.
i work with gradle 2.14.1, oracle java jdk 8 and linux mint 17.3 cinamon. I run the gradle from the command line.
Any idea how to solve this, looks like an inner gradle conflict of some kind, race condition of whom is initialized first.
