-------------------------------------
Summary: Custom environment variables not available when build
started by an SCM change
Key: JENKINS-13466
URL: https://issues.jenkins-ci.org/browse/JENKINS-13466
Project: Jenkins
Issue Type: Bug
Components: scm-sync-configuration
Environment: not applicable

Hi there,
I may have found a sneaky bug. Custom environment variables can be defined by
the user into the general & nodes config:
!custom-env-master.jpg!
!custom-env-slave.jpg!
When a build is triggered by an SCM change, those variables are not available
for SCM plugins.
Let's say that I have a field in my SCM plugin configured with this value:
*$\{JOB_NAME\}_$\{HOSTNAME}_$\{NODE_TYPE\}* If the build is triggered by an SCM
change I get this error:
{code}
Started by an SCM change
Building remotely on vmo426
[ClearCase] ### Begin source code retrieval ###
cleartool error: Illegal characters found in view name : ${NODE_TYPE}. An
environment variable may have not been resolved.
Finished: FAILURE
{code}
Here is the code snipet from my plugin that does that:
{code:Java}
@Override
public boolean checkout(AbstractBuild build, Launcher launcher, FilePath
workspace,
BuildListener listener, File changelogFile) throws IOException,
InterruptedException
{
try {
logger.log("### Begin source code retrieval ###");
String resolvedViewName =
build.getEnvironment(listener).expand(this.viewName);
Pattern pattern = Pattern.compile("(\\$\\{.+?\\})");
Matcher matcher = pattern.matcher(resolvedViewName);
if (matcher.find()) {
String message = "Illegal characters found in view name : %s. " +
"An environment variable may have not been resolved.";
throw new ClearToolError(String.format(message, matcher.group()));
}
{code}
I removed *$\{NODE_TYPE\}* from my SCM configuration to let the build continue.
And the user custom environment variables seem to be injected into the build
environment after the SCM checkout.
{code}

[polling_linux] $ /bin/sh -xe /tmp/hudson7589128551511062241.sh

{code}
Could this be fixed? :)
