| Field Summary | |
| protected String[] | compilerOptions
Compiler-specific options, may be re-initialized by subclasses. |
| Method Summary | |
| public int | compile(String commandLine)
Compiles the files specified (together with options)
with a command line.
Parameters:
commandLine - Command line. | | public int | compile(String[] args)
Compiles the files specified in parameters (together with options).
Parameters:
args - Java Compiler options and source files to compile.Can be null. | | public int | compile(String[] options, File[] files)
Compiles the specified files with specified options.
Parameters:
options - Java Compiler options. | | public int | compile(String[] options, String[] fileNames)
Compiles the specified files with specified options.
Parameters:
options - Java Compiler options. | | protected static File | getFileFromVariable(String variableName, String path, String pattern, String name)
Locates the file from the given environment
variable using the specified parameters.
Parameters:
variableName - Name of the environment variable to use.
Parameters:
path - Path from the directory designated by the specified environmentvariable to the directory, containing the file needed.
Parameters:
pattern - Pattern (regular expression)describing the file that has to be returned.The first file matching this pattern would be returned.
Parameters:
name - Descriptive name of the file being searched for,to be mentioned in exception message if error occurs. | | final public static JavaCompiler | locateJavaCompiler(boolean verbose)
Locates Java Compiler using the following algorithm:
1. | | abstract protected int | run(String[] args)
Runs the compilation process with the specified arguments.
This method must be overridden by the subclasses.
Parameters:
args - Full non-null arguments list. |
| compilerOptions | | protected String[] compilerOptions(Code) | | Compiler-specific options, may be re-initialized by subclasses.
|
| compile | | public int compile(String commandLine) throws JavaCompilerException(Code) | | Compiles the files specified (together with options)
with a command line.
Parameters:
commandLine - Command line. Can be null. Java Compiler return value.
throws:
JavaCompilerException - If some error occurs. |
| compile | | public int compile(String[] args) throws JavaCompilerException(Code) | | Compiles the files specified in parameters (together with options).
Parameters:
args - Java Compiler options and source files to compile.Can be null. Java Compiler return value.
throws:
JavaCompilerException - If some error occurs. |
| compile | | public int compile(String[] options, File[] files) throws JavaCompilerException(Code) | | Compiles the specified files with specified options.
Parameters:
options - Java Compiler options. Can be null.
Parameters:
files - Source files to compile. Can be null. Java Compiler return value.
throws:
JavaCompilerException - If some error occurs. |
| compile | | public int compile(String[] options, String[] fileNames) throws JavaCompilerException(Code) | | Compiles the specified files with specified options.
Parameters:
options - Java Compiler options. Can be null.
Parameters:
fileNames - Source files to compile. Can be null. Java Compiler return value.
throws:
JavaCompilerException - If some error occurs. |
| getFileFromVariable | | protected static File getFileFromVariable(String variableName, String path, String pattern, String name) throws JavaCompilerException(Code) | | Locates the file from the given environment
variable using the specified parameters.
Parameters:
variableName - Name of the environment variable to use.
Parameters:
path - Path from the directory designated by the specified environmentvariable to the directory, containing the file needed.
Parameters:
pattern - Pattern (regular expression)describing the file that has to be returned.The first file matching this pattern would be returned.
Parameters:
name - Descriptive name of the file being searched for,to be mentioned in exception message if error occurs. The first file matching the$variableName/path/pattern.
throws:
JavaCompilerException - If no matching file is found. |
| locateJavaCompiler | | final public static JavaCompiler locateJavaCompiler(boolean verbose) throws JavaCompilerException(Code) | | Locates Java Compiler using the following algorithm:
1. Check if
JavaCompiler.JAVA_COMPILER_CLASS_PROPERTY system property is set.
If set, configure the returned compiler to use the specified class.
Also check
JavaCompiler.JAVA_COMPILER_METHOD_PROPERTY system property,
if set, configure the returned compiler to use the specified method,
otherwise, the
is used.
2. Check if
JavaCompiler.JAVA_COMPILER_EXECUTABLE_PROPERTY system property
is set. If found, configure the returned compiler to use the specified
executable.
3. Check if the Eclipse Compiler class
(
EclipseJavaCompiler.ECLIPSE_COMPILER_CLASS_NAME )
is accessible via classpath, if so, use it to compile.
4. Check if
EclipseJavaCompiler.ECLIPSE_HOME_VARIABLE ECLIPSE_HOME environment variable is set. If set, locate Eclipse compiler JAR
(
EclipseJavaCompiler.ECLIPSE_HOME_VARIABLE$ECLIPSE_HOME /
EclipseJavaCompiler.ECLIPSE_JAR_PATH plugins /
EclipseJavaCompiler.ECLIPSE_JAR_PATTERN org.eclipse.jdt.core_*.jar ),
load (
EclipseJavaCompiler.ECLIPSE_COMPILER_CLASS_NAMEEclipse Compiler class ) from it and use it to compile.
5. Check if
ExecJavaCompiler.JAVA_HOME_VARIABLE JAVA_HOME environment variable is set. If set, search if
ExecJavaCompiler.JAVA_HOME_VARIABLE$JAVA_HOME /
ExecJavaCompiler.JAVA_COMPILER_PATHbin /
ExecJavaCompiler.JAVA_COMPILER_PATTERNjavac executable, if found, execute it to compile.
6. If nothing found, just execute
ExecJavaCompiler.DEFAULT_COMPILER_PROGRAM javac hoping it would be found in the system path.
Parameters:
verbose - If notes and warnings should be printed to System.err. Configured JavaCompiler implementation.
throws:
JavaCompilerException - If compiler could not be found of configured. |
| run | | abstract protected int run(String[] args) throws JavaCompilerException(Code) | | Runs the compilation process with the specified arguments.
This method must be overridden by the subclasses.
Parameters:
args - Full non-null arguments list. Can be empty. Java Compiler return value.
throws:
JavaCompilerException - If some error occurs.
throws:
NullPointerException - If args is null. |
