Classes are searched in the following order:

optionalBootClassPath is not null:
optionalBootClassPath
optionalExtDirs is not null:
optionalExtDirs
classPath
optionalSourcePath is null:

optionalSourcePath is not null:

The file name of a class file that represents class "pkg.Example" is determined as follows:
optionalDestinationDirectory is not NO_DESTINATION_DIRECTORY:
<i>optionalDestinationDirectory</i>/pkg/Example.class
optionalDestinationDirectory is NO_DESTINATION_DIRECTORY:
dir1/dir2/Example.class (Assuming that the file name of the
source file that declares the class was
dir1/dir2/Any.java.)
DEFAULT_WARNING_HANDLE_PATTERNSpublic Compiler(ResourceFinder sourceFinder, IClassLoader iClassLoader, ResourceFinder classFileFinder, ResourceCreator classFileCreator, java.lang.String optionalCharacterEncoding, boolean verbose, boolean debugSource, boolean debugLines, boolean debugVars, WarningHandler optionalWarningHandler)
FIND_NEXT_TO_SOURCE_FILE as the classFileResourceFinder and
CREATE_NEXT_TO_SOURCE_FILE as the classFileResourceCreator.
If it is impossible to check whether an already-compiled class file
exists, or if you want to enforce recompilation, pass
ResourceFinder.EMPTY_RESOURCE_FINDER as the
classFileResourceFinder.

public void setCompileErrorHandler(UnitCompiler.ErrorHandler optionalCompileErrorHandler)
UnitCompiler.ErrorHandler. The default
UnitCompiler.ErrorHandler prints the first 20 compile errors to
System.err and then throws a CompileException.
Passing null restores the default UnitCompiler.ErrorHandler.
Notice that scan and parse errors are not redirected to this UnitCompiler.ErrorHandler,
instead, they cause a CompileException to be thrown.
Also, the Compiler may choose to throw CompileExceptions in certain,
fatal compile error situations, even if an UnitCompiler.ErrorHandler is installed.
In other words: In situations where compilation can reasonably continue after a compile
error, the UnitCompiler.ErrorHandler is called; all other error conditions cause a
CompileException to be thrown.
public boolean compile(java.io.File[] sourceFiles)
throws CompileException,
java.io.IOException
For example, if the source path comprises the directories "A/B" and "../C", then the source file for class "com.acme.Main" is searched in
compile(File[]) or if you invoke
compile(File[]) multiply: In the former case, the source
files may contain arbitrary references among each other (even circular
ones). In the latter case, only the source files on the source path
may contain circular references, not the sourceFiles.
This method must be called exactly once after object construction.
Compile errors are reported as described at
setCompileErrorHandler(UnitCompiler.ErrorHandler).

If optionalDestinationDirectory is non-null, the returned path is the
optionalDestinationDirectory plus the package of the class (with dots replaced
with file separators) plus the class name plus ".class". Example:
"destdir/pkg1/pkg2/Outer$Inner.class"
If optionalDestinationDirectory is null, the returned path is the
directory of the sourceFile plus the class name plus ".class". Example:
"srcdir/Outer$Inner.class"
