SublimeLinter-javac

This linter plugin for SublimeLinter provides an interface to javac. It will be used with files that have the “Java” syntax.

Please note that because javac requires a complete directory context in order to work, this linter plugin currently will only lint a file when it has been saved.

Installation

SublimeLinter must be installed in order to use this plugin.

Please use Package Control to install the linter plugin.

Before using this plugin, ensure that javac (JDK 1.7+) is installed on your system. javac is part of the java developer SDK, which can be downloaded here.

Please make sure that the path to javac is available to SublimeLinter. The docs cover troubleshooting PATH configuration.

Settings

• SublimeLinter settings: http://sublimelinter.com/en/latest/settings.html
• Linter settings: http://sublimelinter.com/en/latest/linter_settings.html

Additional SublimeLinter-javac settings:

Valid rule names are: all, cast, classfile, deprecation, dep-ann, divzero, empty, fallthrough, finally, options, overrides, path, processing, rawtypes, serial, static, try, unchecked, varargs, -cast, -classfile, -deprecation, -dep-ann, -divzero, -empty, -fallthrough, -finally, -options, -overrides, -path, -processing, -rawtypes, -serial, -static, -try, -unchecked, -varargs, none.

For example, to ignore deprecation warnings for all files in a project, you would add this to the linter settings:

"javac": {
    "lint": "all,-deprecation"
}

Passing options to javac

In order to configure javac options like the class path, source path, or file encoding, the args setting can be used.

A full list of available options is given here.

For example, the following configuration defines the source file encoding, includes the two libraries lib/some_lib.jar and lib/some_other_lib.jar in the classpath, and defines src/ as the project's source path:

"args": [
    "-encoding", "UTF8",
    "-cp", "${folder}/lib/some_lib.jar:${folder}/lib/some_other_lib.jar",
    "-sourcepath", "${folder}/src/"
]

Note that options and their values must be separate elements in the array (i.e. "args": ["-sourcepath", "/path/to/src"] does work, while "args": ["-sourcepath /path/to/src"] does not work).

Classpath

To configure classpaths with a lot of elements, the classpath setting may be used alternatively or in addition to args.

If *-sourcepath is unspecified* (in args), -classpath can also be used to configure source paths.

The above example would look like this:

"args": ["-encoding", "UTF8"],
"classpath": [
    "${folder}/lib/some_lib.jar",
    "${folder}/lib/some_other_lib.jar",
    "${folder}/src/", // sourcepath elements go here, too
]

Project-specific options

Settings like the class path often only apply to one specific project. The general SublimeLinter documentation also explains how to specify project-specific settings in the sublime-project file.

For the example above, such a project file could look like this: “ { "folders”: [ { “path”: “.” } ], “settings”: { “SublimeLinter.linters.javac.lint”: “all”, “SublimeLinter.linters.javac.args”: [“-encoding”, “UTF8”], “SublimeLinter.linters.javac.classpath”: [ “${folder}/lib/some_lib.jar”, “${folder}/lib/some_other_lib.jar”, “${folder}/src/”, ] } }
