在脚本中将PASSWORD凭据变量从Jenkins传递到sshpass

Question

I've setup some global credentials in jenkins, username password type.

I've now got to scp a file over to a target server inside my pipeline.

For arguments sake, lets say my password variable is secretpassword.

Does anyone know how to get the password to work properly with sshpass?

Here's the gist of what I'm trying to do

sh '''
sshpass -p'${PASSWORD}' scp  ${WORKSPACE}/target/citest-1.0-SNAPSHOT.jar root@target_service:/
'''

Whatever I try I can't seem to get the syntax right for passing the password to sshpass

If I do the following, it works fine

sh '''
sshpass -p 'secretpassword' scp ${WORKSPACE}/target/citest-1.0-SNAPSHOT.jar root@target_service:/
'''

So I'm obviously just messing up how to get the PASSWORD env variable to spit out properly into the single quotes.

I seem to have tried a few thousand options so far, does anyone have any bright ideas?

Thanks in advance

Answer 1

Try without single quotes.

sshpass -p ${PASSWORD} scp ${WORKSPACE}/target/citest-1.0-SNAPSHOT.jar root@target_service:/

Is there any specific reason to keep it in single Quotes? because single quote will not interpolate variable.

Answer 2

Use ''' only if you have multiple sh commands to run, if it just a single command then do it like so and it should work fine

 sh "sshpass -p ${PASSWORD} scp  ${WORKSPACE}/target/citest-1.0-SNAPSHOT.jar root@target_service:/ "

if you need to use '''

then use it without the single quotes

sh '''
sshpass -p ${PASSWORD} scp  ${WORKSPACE}/target/citest-1.0-SNAPSHOT.jar root@target_service:/
'''
