Examples of JavaCompiler

com.caucho.java.JavaCompiler
Compiles Java source, returning the loaded class.
com.sun.tools.javac.main.JavaCompiler
This class could be the main entry point for GJC when GJC is used as a component in a larger software system. It provides operations to construct a new compiler, and to run a new compiler on a set of source files.
This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

javax.tools.JavaCompiler

t for first compilation task File[] files2 = ... ; // input for second compilation task JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null); {@code Iterable} compilationUnits1 =fileManager.getJavaFileObjectsFromFiles( {@linkplain java.util.Arrays#asList Arrays.asList}(files1)); compiler.getTask(null, fileManager, null, null, null, compilationUnits1).call(); {@code Iterable} compilationUnits2 =fileManager.getJavaFileObjects(files2); // use alternative method // reuse the same file manager to allow caching of jar files compiler.getTask(null, fileManager, null, null, null, compilationUnits2).call(); fileManager.close();

{@link DiagnosticCollector}

Used to collect diagnostics in a list, for example:

 {@code Iterable} compilationUnits = ...;JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); {@code DiagnosticCollector diagnostics = new DiagnosticCollector();}StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null); compiler.getTask(null, fileManager, diagnostics, null, null, compilationUnits).call(); for ( {@code Diagnostic} diagnostic : diagnostics.getDiagnostics())System.out.format("Error on line %d in %s%n", diagnostic.getLineNumber(), diagnostic.getSource().toUri()); fileManager.close();

{@link ForwardingJavaFileManager}, {@link ForwardingFileObject}, and {@link ForwardingJavaFileObject}

Subclassing is not available for overriding the behavior of a standard file manager as it is created by calling a method on a compiler, not by invoking a constructor. Instead forwarding (or delegation) should be used. These classes makes it easy to forward most calls to a given file manager or file object while allowing customizing behavior. For example, consider how to log all calls to {@linkplain JavaFileManager#flush}:

 final  {@linkplain java.util.logging.Logger Logger} logger = ...;{@code Iterable} compilationUnits = ...;JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); StandardJavaFileManager stdFileManager = compiler.getStandardFileManager(null, null, null); JavaFileManager fileManager = new ForwardingJavaFileManager(stdFileManager) { public void flush() throws IOException { logger.entering(StandardJavaFileManager.class.getName(), "flush"); super.flush(); logger.exiting(StandardJavaFileManager.class.getName(), "flush"); } }; compiler.getTask(null, fileManager, null, null, null, compilationUnits).call();

{@link SimpleJavaFileObject}

This class provides a basic file object implementation which can be used as building block for creating file objects. For example, here is how to define a file object which represent source code stored in a string:

 / * A file object used to represent source coming from a string. {@code *}/ public class JavaSourceFromString extends SimpleJavaFileObject { / * The source code of this "file". {@code *}/ final String code; / * Constructs a new JavaSourceFromString. *  {@code @}param name the name of the compilation unit represented by this file object *  {@code @}param code the source code for the compilation unit represented by this file object {@code *}/ JavaSourceFromString(String name, String code) { super( {@linkplain java.net.URI#create URI.create}("string:///" + name.replace('.','/') + Kind.SOURCE.extension), Kind.SOURCE); this.code = code; } {@code @}Override public CharSequence getCharContent(boolean ignoreEncodingErrors) { return code; } }

net.sf.jsptest.compiler.java.JavaCompiler
The interface for Java compiler implementations. @author Lasse Koskela
org.apache.commons.jci.compilers.JavaCompiler
The general compiler interface. All compilers implementing this interface should read the resources from the reader and store the java class files into the ResourceStore. The actual compilation language does not matter. But the contract is that the result of the compilation will be a class file. If possible the compiler should notify the optional CompilationProblemHandler as soon as a problem is found. @author tcurdt
