Constant Field Values

compileErrors

private boolean compileErrors

Keeps track of if we get compile errors in incremental mode

recompileMode

@Parameter(property="recompileMode",
           defaultValue="all")
protected java.lang.String recompileMode

Recompile mode to use when sources were previously compiled and there is at least one change: "modified-only" => only modified sources are recompiled (pre 2.13 behavior), "all" => all sources are recompiled, "incremental" => incrementally recompile modified sources and other affected sources.

notifyCompilation

@Parameter(property="notifyCompilation",
           defaultValue="true")
private boolean notifyCompilation

notifyCompilation if true then print a message "path: compiling" for each root directory or files that will be compiled. Useful for debug, and for integration with Editor/IDE to reset markers only for compiled files.

_lastCompileAt

private long _lastCompileAt

incremental

private SbtIncrementalCompiler incremental

compileOrder

@Parameter(property="compileOrder",
           defaultValue="mixed")
private java.lang.String compileOrder

Compile order for Scala and Java sources for sbt incremental compile. Can be Mixed, JavaThenScala, or ScalaThenJava.

useZincServer

@Parameter(property="useZincServer",
           defaultValue="false")
private boolean useZincServer

Use zinc server for incremental recompilation.

zincPort

@Parameter(property="zincPort",
           defaultValue="3030")
private int zincPort

Zinc server port, if running with incremental zinc server mode.

zincHost

@Parameter(property="zincHost",
           defaultValue="127.0.0.1")
private java.lang.String zincHost

Zinc server host, if running with incremental zinc server mode. Defaults to 127.0.0.1.

addZincArgs

@Parameter(property="addZincArgs")
private java.lang.String addZincArgs

Additional parameter to use to call zinc server It is a pipe '|' separated list of arguments, so it can be used from command line ("-DaddZincArgs=arg1|arg2|arg3|...").
