Logging (log4j, etc)

Auto import / initialize

While editing a java source file, if you start to create a logging statement (log. or logger.), the logging plugin will attempt to perform the appropriate initialization (imports, static variable) for the configured logging implementation.

Eclim provides a handful of templates for the most widely used implementations (commons-logging, slf4j, log4j, and jdk). However, if you happen to use an alternate logging framework, or perhaps a home grown framework, eclim also provides the means to supply a custom template. To utilize it, simply set the setting to “custom” and add your template to ~/.eclim/resources/jdt/templates/logger.gst. Two variables will be supplied to your template: var, which is the logger instance variable, and class, which is the class name of the current class you are implementing.

Here is an example which eclim uses for its logger implementation:

import org.eclim.logging.Logger;
private static final Logger ${var} = Logger.getLogger(${class}.class);

After performing the necessary variable substitution, eclim will take any imports and insert them amongst your existing import statements. The remaining code will be inserted after your class definition.


Vim Settings

  • g:EclimLoggingDisabled (Default: 0) - If set to a value greater than 0, then this plugin will be disabled.

Eclim Settings

  • (Default: “commons-logging”) - Determines which logging implementation to use.

    Possible values include “commons-logging”, “slf4j”, “log4j”, “jdk”, and “custom”.

  • (Default: ‘logger.gst’) - Determines the name of the template to use for the custom logger. The name must be a file name relative to ~/.eclim/resources/jdt/templates/.



When editing a log4j xml file eclim will default to validating the file when it is written. Any errors will be added to the current window’s location list (:help location-list) and their corresponding line number noted via Vim’s sign functionality.

Eclim also combines the above validation with xml validation to validate that the file is well formed.

If you do not want your log4j files validated automatically when saved, you can set the g:EclimLog4jValidate variable described in the configuration section below.

Whether or not auto validation has been enabled, eclim also exposes the command :Validate to manually execute the validation of the file.


Vim Settings

  • g:EclimLog4jValidate (Default: 1) - If set to 0, disables validation when saving the file.
