Re: Is there a way to read a string (version numbers) from a file into jenkins variable?

Thanks Jan. The Envfile plugin doesn't work for me as it requires the
java property format. My version file is just 3 digits in the plain
text file.

I could go with the second option. I need the version number in
post-build action, where I'm sending the files to a remote server
using scp. I need the version number included in the remote path. Is
there a way I can run any script in post-build actions?

By build steps, you mean pre-build, build, post-build? So if I set any
environment variables using Ant (or Phing) in build step, it will not
exist in post-build actions? Thanks.

Cheers,
Pan

 Hi,

 you could try the Jenkins Environment File Plugin
 https://wiki.jenkins-ci.org/display/JENKINS/Envfile+Plugin

 Else you would have to run some string manipulation to get the value
 into a file and execute it at each build step like you would assign an
 environment variable.
 In DOS it would be a content like: SET var_name=var_value.
 You have to execute it at each build step which needs the value as the
 variable is destroyed when the build step is done.

 Take care

You could create another file with the version number in the java
property (key=value) format.
Then you can use the EnvInject plugin to inject the environment
variable (MY_NEW_VAR) into your job/build.
The advantage of this approach is that the variable can be visible
throughout the whole job/build.
You just enter the path/myVersion.txt in the Properties File field of
the plugin.

Alternatively just use DOS, eg: To place the first line of a file into
a variable, do this
Set /P MyVar=aFilename
The downside to this later approach is that you may have to repeat it
if you open several shells.
