I've placed the path to the ant installation in the PATH, logged off, logged back on and re-launched the slave, but your build still produces the same error. It appears this started failing recently, yet Ant wasn't changed on the slave. How do you presume that this is an ant problem? From the stack trace, it looks as if Hudson didn't even get to the point where it would execute our configured script, but rather already failed while trying to get the Ant runtime: at hudson.tasks.Ant$AntInstallation.forNode(Ant.java:380) at hudson.tasks.Ant.perform(Ant.java:149) By now the problem seems to have disappeared. Do we know now that this can't happen again? @Denis: Just out of curiosity: Are you on this problem alone, or do you get support by the Huson team? The Hudson teams provides assistance if we request it. At this point, we'd need something reproducible. (In reply to comment #3) > The Hudson teams provides assistance if we request it.

The problem is back: We are getting exactly the same stack trace again [1] - and this reliably for 1 day/5 builds [2]. [1] https://hudson.eclipse.org/hudson/job/tycho-its-win-nightly/265/console [2] https://hudson.eclipse.org/hudson/job/tycho-its-win-nightly/261/console Can you provide more info about what the JSON payload is, and where it comes from? Am I supposed to know how the Ant command is marshalled to the Windows slave? The job configuration [1] simply has an "Invoke ANT" build step with the build file $WORKSPACE/prepareBuild.xml But as before, the problem disappeared in the meanwhile (since build 266 [2]).

I don't know -- I don't know how your build works, so I'm just wondering what JSON is causing it to explode.
You've chosen "auto install Ant 1.7.1" -- have you tried simply using the ant 1.7.1 that is already in the available choices?
(In reply to comment #8) > You've chosen "auto install Ant 1.7.1" -- have you tried simply using the ant > 1.7.1 that is already in the available choices? We just need any Ant version - so if we are supposed to use "ant 1.7.1", that is fine with us. Unfortunately this makes things worse [1]. The build now fails with the message FATAL: Cannot find executable from the choosen Ant installation "apache-ant-1.7.1" "(Default)" as Ant Version works. Can you recommended this setting? [1] https://hudson.eclipse.org/hudson/job/tycho-its-win-nightly/277/console Use the Ant 1.8.3, as that's the only version installed on the Windows slave. -M. 1.8.3 is not offered in the dropdown list, the highest version number is 1.8.2. Sorry I need to read the labels on the slave config page. On the windows slave Ant 1.8.2 is mapped to a local install of Ant 1.8.3. -M. This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.

It looks to me, as if there is something wrong with the setup of the Windows slave of hudson.eclipse.org. From the stack trace, I suppose that the slave is not able to find the configured Ant installation. Stack trace: FATAL: A JSONObject text must begin with '{' at character 0 of net.sf.json.JSONException: A JSONObject text must begin with '{' at character 0 of at net.sf.json.util.JSONTokener.syntaxError(JSONTokener.java:499) at net.sf.json.JSONObject._fromJSONTokener(JSONObject.java:972) at net.sf.json.JSONObject._fromString(JSONObject.java:1201) at net.sf.json.JSONObject.fromObject(JSONObject.java:165) at net.sf.json.JSONObject.fromObject(JSONObject.java:134) at hudson.model.DownloadService$Downloadable.getData(DownloadService.java:197) at hudson.tools.DownloadFromUrlInstaller$DescriptorImpl.getInstallables(DownloadFromUrlInstaller.java:154) at hudson.tools.DownloadFromUrlInstaller.getInstallable(DownloadFromUrlInstaller.java:59) at hudson.tools.DownloadFromUrlInstaller.performInstallation(DownloadFromUrlInstaller.java:68) at hudson.tools.InstallerTranslator.getToolHome(InstallerTranslator.java:61) at hudson.tools.ToolLocationNodeProperty.getToolHome(ToolLocationNodeProperty.java:99) at hudson.tools.ToolInstallation.translateFor(ToolInstallation.java:149) at hudson.tasks.Ant$AntInstallation.forNode(Ant.java:380) at hudson.tasks.Ant.perform(Ant.java:149) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:630) at hudson.model.Build$RunnerImpl.build(Build.java:175) at hudson.model.Build$RunnerImpl.doRun(Build.java:137) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:429) at hudson.model.Run.run(Run.java:1367) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:145) Full log: https://hudson.eclipse.org/hudson/job/tycho-its-win-nightly/217/console
