Since an update to version 1.6 and Hudson 1.299 the DISPLAY variable is not set
during the build process anymore. We try to test a SWT application wich requires this env-var or refuses to start. Below is first the SWT exception - with a cryptic error message but this means not DISPLAY is found. Below the trace are all system properties printed by Sytem.getProperties().list(...)Exception in thread "main" org.eclipse.swt.SWTError: No more handles

User: Kohsuke Kawaguchi Path: src/main/java/hudson/maven/AbstractMavenBuild.java src/main/java/hudson/maven/MavenModuleSetBuild.java Log: Mutating 'envVars' returned from getEnvironment() creates a bad precedent.It is better to just recompute the envVars, which will reflect all the added environments.

Relevant conversation:
(11:31:53 AM) KostyaSha: kohsuke, while windows is eating your IO, could you advice with ?
(11:34:27 AM) kohsuke: KostyaSha: the bug looks legit, but I'm not sure about the fix. Basically I agree with Jesse's comment (11:35:35 AM) KostyaSha: kohsuke, this broken by design i think, it should be a good idea to share envvars for builders. This should also reduce .getEnvironments() calls (11:36:33 AM) KostyaSha: kohsuke, is there any place where they maybe safely shared? (11:37:03 AM) kohsuke: I'm afraid I don't understand the notion of "sharing envvars" (11:37:35 AM) kohsuke: It gets computed from various things, and I thought EnvironmentContributingAction is a part of it (11:38:44 AM) KostyaSha: kohsuke, yes, and they are stored in envvars variable, then job calls prebuilders that modifies EnvironmentContributingAction and then job calls maven build with not updated envvars content (11:39:05 AM) kohsuke: then it should just call EnvVars envVars = getEnvironment(listener); again (11:39:50 AM) KostyaSha: kohsuke, i not sure that there is no any specific changes with envvars after first getEnvironment(listener) call and before prebuilders (11:40:30 AM) KostyaSha: i compared on my local instance and this should work, but i not sure... potentially some changes to envvars maybe lost... (11:40:31 AM) kohsuke: Basically, one should never modify what Run.getEnvironment() returned (11:40:51 AM) kohsuke: If the map returned is missing some desirable entries, then it should be fixing by having the getEnvironment() implementation add them (11:41:11 AM) kohsuke: It looks to me that this change violates that idea (11:42:02 AM) KostyaSha: i like idea of refreshing with simple call to getEnvironment(listener) (11:42:03 AM) kohsuke: if environment-contributing subset of rootBuild.actions should be a part of the env vars, according to the above principle it should be done in the getEnvironment() method (11:42:52 AM) kohsuke: (Also, let's not print out random stuff into "logger.println" that most users would not care (11:43:02 AM) kohsuke: Those should be j.u.logging statements) (11:43:28 AM) KostyaSha: kohsuke, yeah this logger not needed of course (11:44:55 AM) KostyaSha: kohsuke, what this part do? (11:45:44 AM) kohsuke: That looks wrong to me, too, for the same reason (11:45:49 AM) kohsuke: All right, you convinced me to open this in IDE (11:46:03 AM) kohsuke: Screw the preparation for the meeting (11:47:29 AM) kohsuke: Wow, that line has jglick fixing HUDSON-3502 (11:47:31 AM) jenkins-admin: :Xvnc does not set the DISPLAY environment (Closed) (11:48:06 AM) KostyaSha: 0_o (11:48:17 AM) kohsuke: From 2009 (11:49:34 AM) KostyaSha: kohsuke, and the next block is also added for resolving variables (11:49:42 AM) kohsuke: Yep (11:50:28 AM) KostyaSha: so after every step we need recalculate changes... so easy to allow do direct modifications of envvars i think转载地址：http://uojab.baihongyu.com/
When I create a simple job and output the 'env' cmd on the shell the DISPLAY is
set. But the strange thing in that is that during my test (surefire) all hudson specific env-vars are set (like HUDSON_HOME, HUDSON_URL, ...) only the DISPLAY is missing.
