[yocto] Error while trying to read environment variable from a recipe file

[Bipnesh, Abhinav (Abhinav)]

Hi All,

I was trying to read some of the environment variables from a recipe file using below python code

PACKAGES = "{TEST_PACKAGE}"
python __anonymous () {
    packages = []
    buildScriptVersion = os.environ['MajorVersion'] + "." + os.environ['MinorVersion']
    buildID = os.environ['BuildID']
    buildOffSet = os.environ['BuildOffsetNum']
    buildNum = int(buildID) - int(buildOffSet)
    if buildNum <= 0:
        buildNum = 1
    Num = os.environ['Num']
    version = buildScriptVersion + "." + sprintNum + "." + str(buildNum)
    packageName = "test-" + version
    d.setVar("TEST_PACKAGE", " ".join(packages))
}

But while running I am getting below error

0001:def __anon_29__test_bb(d):
     0002:    packages = []
*** 0003:    buildScriptVersion = os.environ['MajorVersion'] + "." + os.environ['MinorVersion']
     0004:    buildID = os.environ['BuildID']
     0005:    buildOffSet = os.environ['BuildOffsetNum']
     0006:    buildNum = int(buildID) - int(buildOffSet)
     0007:    if buildNum <= 0:
File: '/usr/lib64/python2.7/UserDict.py', lineno: 23, function: __getitem__
     0019:        if key in self.data:
     0020:            return self.data[key]
     0021:        if hasattr(self.__class__, "__missing__"):
     0022:            return self.__class__.__missing__(self, key)
*** 0023:        raise KeyError(key)
     0024:    def __setitem__(self, key, item): self.data[key] = item
     0025:    def __delitem__(self, key): del self.data[key]
     0026:    def clear(self): self.data.clear()
     0027:    def copy(self):
Exception: KeyError: 'MajorVersion'

So any thoughts to fix this issue. As we need to have a package name with such variable which will be set in the environment at run time.

Thanks,
Abhinav
