Greetings! We are trying to use the Teamcity plugin with the "checkout on agent" configuration. This configuration works fine on Windows, but for a Linux agent the checkout does not work. The build fails event before the first build step: Looking at the teamcity-agent.log the next exception trace appears: [2019-10-01 17:54:40,649] ERROR - pl.patch.ProjectSourcesOnAgent - Problem while checkout on agent java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.lang.SystemUtils at com.codicesoftware.plugins.teamcity.PathUtils.isFileInSymlinkContained(PathUtils.java:34) at com.codicesoftware.plugins.teamcity.PathUtils.getCanonicalPath(PathUtils.java:16) at com.codicesoftware.plugins.teamcity.WorkspaceManager.ensureWorkspaceExists(WorkspaceManager.java:21) at com.codicesoftware.plugins.teamcity.PlasticAgentVcsSupport.updateSources(PlasticAgentVcsSupport.java:67) at jetbrains.buildServer.agent.impl.vcs.AgentVcsManagerExImpl$CheckoutSupportImpl.updateSources(AgentVcsManagerExImpl.java:108) at jetbrains.buildServer.agent.impl.patch.ProjectSourcesOnAgent$1.run(ProjectSourcesOnAgent.java:186) at java.base/java.lang.Thread.run(Thread.java:834) [2019-10-01 17:54:40,651] WARN - l.patch.AbstractSourcesUpdater - Error while checkout on agent: Problem while checkout on agent: java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.lang.SystemUtils jetbrains.buildServer.vcs.VcsException: Problem while checkout on agent: java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.lang.SystemUtils at jetbrains.buildServer.agent.impl.patch.ProjectSourcesOnAgent$1.run(ProjectSourcesOnAgent.java:192) at java.base/java.lang.Thread.run(Thread.java:834) Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.lang.SystemUtils at com.codicesoftware.plugins.teamcity.PathUtils.isFileInSymlinkContained(PathUtils.java:34) at com.codicesoftware.plugins.teamcity.PathUtils.getCanonicalPath(PathUtils.java:16) at com.codicesoftware.plugins.teamcity.WorkspaceManager.ensureWorkspaceExists(WorkspaceManager.java:21) at com.codicesoftware.plugins.teamcity.PlasticAgentVcsSupport.updateSources(PlasticAgentVcsSupport.java:67) at jetbrains.buildServer.agent.impl.vcs.AgentVcsManagerExImpl$CheckoutSupportImpl.updateSources(AgentVcsManagerExImpl.java:108) at jetbrains.buildServer.agent.impl.patch.ProjectSourcesOnAgent$1.run(ProjectSourcesOnAgent.java:186) ... 1 more Plugin version: Do you know why may this be happening? I have looked at the plugin folder in the agent and the commons-lang.jar is there. Regards!

Hello guys, we are expiriencing issues while trying to download changes from Plastic repositories from TeamCity 8.0.6. The issue it that we just can't download full repository and build just fails on step of checking changes. See full build log attached. Here I want to ask few questions: 1) Please look at the first line of the log. Checking for changes takes about 20 minutes and that is short one. Now I have a build that hung on that state for a 1 hour. What should we do in such case? How can we debug what is wrong? 2) On each of 3 attempts, repository data has been transeffered (see line [17:23:40]Repository sources transferred: 8.84 GB total), but immediately after that checking changes fails with: [17:23:41]Will repeat attempt when server will be available, number of attempts left: 2 So why does oit fail? When can we see any error information? 3) Please explain the error in 3rd attempt.
