How to prevent Jenkins from adding single quotes to parameterized vlaues

[no...@gmx.com]

I basically have a string parameter that contains values from other parameter fields, which I then use again in the Execute shell command.
However, Jenkins adds single quotes in erroneous places within that string, which makes the executing application unable to parse the arguments.

Example:

Name: OPTS
Default Value: -e "arg1=${VAR1} arg2=${VAR2} arg3={VAR3}"
	
Execute shell
Command: ./build_app $OPTS


Console Output:
./build_app -e '"arg1=value1' arg2=value2 'arg3=value3"'

Notice the placement of the single quotes preceding the opening double quote and after value1, and before arg3 and after the closing double quote. These were not added by me.

I have also tried:
Command: ./build_app $(echo $OPTS)

but it renders the same results.

I am trying to figure out if this is expected behavior or if this is an actual bug.
The only other mention of this issue was found here (which went unanswered): http://stackoverflow.com/questions/28260083/how-do-i-prevent-jenkins-from-single-quoting-the-parameterized-value

I am currently running Jenkins 1.642.


Thanks!

I've also tried doing this:
Name: OPTS
Default Value: -o tmp -e "arg1=${VAR1} arg2=${VAR2} arg3=${VAR3}"

Execute shell command:
ARGS=$(echo $OPTS)
./build_app $ARGS

Console Output:

++ echo -o tmp -e '"arg1=value1' arg2=value2 'arg3=value3"'
+ ARGS='-o tmp -e "arg1=${VAR1} arg2=${VAR2} arg3={VAR3}"'
+ ./build_app  -o tmp -e '"arg1=value1' arg2=value2 'arg3=value3"'

So it seems the parameter variable itself doesn't contain the single quotes, just when it's being referenced. And the single quotes only appear around wherever there's double quotes in the string.

I answered this on IRC. Here's basically the same answer again:

It IS adding the single quotes to build parameters!
