hello again,


I tried adding :



python do_package_prepend() {

d.setVar('PKGV', d.getVar("JENKINS_VERSION", True)) prin= t d.getVar('PKGV',True)

Hi Chris= topher,

PKGV seems very interesting to me. is there out there any example= to follow ?

if I add something like that at the end of do_compile task should it w= ork?

do_compile(){
#..... do stuff and get in myVersion the revision 

{@setVar("PKGV","${myVersion}")}

}


Thanks .
