Installation

Ensure a working JDK is available in your environment (see FAQ) then enter the following on your command line:

apm install linter-javac

Or Atom ➔ Preferences... ➔ Packages ➔ Search for "linter-javac".

Settings

You can configure linter-javac by using the GUI (recommended - the GUI offers a description and valid defaults) or by editing your ~/.atom/config.cson (or Atom ➔ Open Your Config):


"linter-javac":
  javaExecutablePath: "javac"
  additionalClasspaths: "C:\Users\JohnDoe"
  additionalJavacOptions: "-verbose -d C:\java-class-cache"
  classpathFilename: ".acme-inc-classpaths"
  javacArgsFilename: "acme-inc-argfile"

Example-Configuration, see our Wiki or the config-GUI for further information.

To configure linter-javac on a per project-base, we currently encourage you using the project-manager package.

Classpath

The currently implemented .classpath-file format conflicts with the Eclipse-based file format. Therefore this implementation will be replaced in the far future.
We are aware that configuring classpath-information is the most important (and annoying) issue in linting source-files right - we are working hard to make our planned improvement imperceptible for you. We will keep you informed.

~~It is strongly recommended that you~~ You may configure your classpath via a so called classpath-file which by default is named .classpath (you can change the filename in the Atom-preferences).

The linter starts searching for your classpath-file in the directory where the source file resides which get's linted. If there is no matching classpath-file the search is continued wandering the file-tree up, until a classpath-file is found or the project-folder would be left.

You may place any directories classpath-file, delimited by your platform-specific path-dlimiter (:/;):

.:./lib/junit.jar

A linter configured by the above example will execute javac in the directory where the classpath-file resides, so that relative paths will be resolved in dependency to the classpath-file-position.
