maven - read version number from property file

Question

I`m trying to read my build version number from a text file, and then assign it to the generated package name: myRelease-1.1.1.apk where the build number is manually set int

Answer 1

As you already got pom.xml, you don't need another extra properties file for define such a simple property, use POM's properties tag and override the default build finalName:

  1.1.1


  ... ...
  ${project.artifactId}-${final.build.version}
  ... ...

If you use maven sign and zipalign your final apk at release stage, and want to override the final name here, use:

  
    
      com.jayway.maven.plugins.android.generation2
      android-maven-plugin
      true
      true
      
        true
        
          false
        
        
          true
          ${project.build.directory}/${project.artifactId}-${final.build.version}.apk
          ${project.build.directory}/${project.artifactId}-${final.build.version}-signed-aligned.apk
        
        
          
            
              alignApk
              package
              
                zipalign
              
            
          
      
   

EDIT:
If you have to use properties file, use properties-maven-plugin, check out similar SO question here.

Hope this help.
