>From unknown reason files under /var/lib/jenkins were removed from my Jenkins master machine. It reproduced three times.
To enable Jenkins to work I had to restore jenkins jobs. The error I see in system log - Caused: java.util.MissingResourceException: Unable to load resource jar:file:/var/lib/jenkins/plugins/mask-passwords/WEB-INF/lib/mask-passwords.jar!/com/michelin/cio/hudson/plugins/passwordparam/PasswordParameterDefinition.properties com.michelin.cio.hudson.plugins.passwordparam.PasswordParameterDefinition$ParameterDescriptorImpl.getDisplayName(PasswordParameterDefinition.java:75) Caused: java.lang.reflect.InvocationTargetException It looks like it connect to mask password plugin - should I remove this plugin to solve it?
