With 1.29 update $PATH variable is not redefined:

console:
--------------------------
[EnvInject] - Executing scripts and injecting environment variables after the SCM step.
[EnvInject] - Injecting as environment variables the properties content
PATH=/some/dir/:$PATH
TEST_VAR=aaaaa

[EnvInject] - Variables injected successfully.
[EnvInject] - Unset unresolved 'PATH' variable.
[testPATH] $ /bin/sh -xe /tmp/hudson2831645515572899066.sh
+ echo /usr/local/bin:/bin:/usr/bin
/usr/local/bin:/bin:/usr/bin
+ echo aaaaa
aaaaa
--------------------------
I need to redefine $PATH to use within actual build.
