Examples with BashStep com.facebook.buck.shell.BashStep used on opensource projects

Example 1 with BashStep

use of com.facebook.buck.shell.BashStep in project buck by facebook.

the class BaseCompileToJarStepFactory method addPostprocessClassesCommands.

/**
   * Adds a BashStep for each postprocessClasses command that runs the command followed by the
   * outputDirectory of javac outputs.
   *
   * The expectation is that the command will inspect and update the directory by
   * modifying, adding, and deleting the .class files in the directory.
   *
   * The outputDirectory should be a valid java root.  I.e., if outputDirectory
   * is buck-out/bin/java/abc/lib__abc__classes/, then a contained class abc.AbcModule
   * should be at buck-out/bin/java/abc/lib__abc__classes/abc/AbcModule.class
   *
   * @param filesystem the project filesystem.
   * @param postprocessClassesCommands the list of commands to post-process .class files.
   * @param outputDirectory the directory that will contain all the javac output.
   * @param declaredClasspathEntries the list of classpath entries.
   * @param bootClasspath the compilation boot classpath.
