/**
* Defines the implementation of the
* {@linkplain javax.tools.ToolProvider#getSystemJavaCompiler system Java compiler}
* and its command line equivalent, {@index javac javac tool}.
*
* The {@code com.sun.source.*} packages provide the {@index "Compiler Tree API"}:
* an API for accessing the abstract trees (ASTs) representing Java source code
* and documentation comments, used by javac, javadoc and related tools.
*
*
javac
*
*
* This module provides the equivalent of command-line access to javac
* via the {@link java.util.spi.ToolProvider ToolProvider} and
* {@link javax.tools.Tool} service provider interfaces (SPIs),
* and more flexible access via the {@link javax.tools.JavaCompiler JavaCompiler}
* SPI.
*
* Instances of the tools can be obtained by calling
* {@link java.util.spi.ToolProvider#findFirst ToolProvider.findFirst}
* or the {@linkplain java.util.ServiceLoader service loader} with the name
* {@code "javac"}.
*
*
* In addition, instances of {@link javax.tools.JavaCompiler.CompilationTask}
* obtained from {@linkplain javax.tools.JavaCompiler JavaCompiler} can be
* downcast to {@link com.sun.source.util.JavacTask JavacTask} for access to
* lower level aspects of javac, such as the
* {@link com.sun.source.tree Abstract Syntax Tree} (AST).
*
* This module uses the {@link java.nio.file.spi.FileSystemProvider
* FileSystemProvider} API to locate file system providers. In particular,
* this means that a jar file system provider, such as that in the
* {@code jdk.zipfs} module, must be available if the compiler is to be able
* to read JAR files.
*
*
Options and Environment Variables
*
* The full set of options and environment variables supported by javac
* is given in the javac Tool Guide.
* However, there are some restrictions when the compiler is invoked through
* its API.
*
*
* The {@code -J} option is not supported.
* Any necessary VM options must be set in the VM used to invoke the API.
* {@code IllegalArgumentException} will be thrown if the option
* is used when invoking the tool through the {@code JavaCompiler} API;
* an error will be reported if the option is used when invoking
* javac through the {@link java.util.spi.ToolProvider ToolProvider}
* or legacy {@link com.sun.tools.javac.Main Main} API.
*
*
The "classpath wildcard" feature is not supported.
* The feature is only supported by the native launcher.
* When invoking the tool through its API, all necessary jar
* files should be included directly in the {@code --class-path}
* option, or the {@code CLASSPATH} environment variable.
* When invoking the tool through its API, all components of the
* class path will be taken literally, and will be ignored if there
* is no matching directory or file. The {@code -Xlint:paths}
* option can be used to generate warnings about missing components.
*
*
*
* The following restrictions apply when invoking the compiler through
* the {@link JavaCompiler} interface.
*
*
* Argument files (so-called @-files) are not supported.
* The content of any such files should be included directly
* in the list of options provided when invoking the tool
* though this API.
* {@code IllegalArgumentException} will be thrown if
* the option is used when invoking the tool through this API.
*
*
The environment variable {@code JDK_JAVAC_OPTIONS} is not supported.
* Any options defined in the environment variable should be included
* directly in the list of options provided when invoking the
* API; any values in the environment variable will be ignored.
*
*
Options that are just used to obtain information (such as
* {@code --help}, {@code --help-extended}, {@code --version} and
* {@code --full-version}) are not supported.
* {@link IllegalArgumentException} will be thrown if any of
* these options are used when invoking the tool through this API.
*
*
- Path-related options depend on the file manager being used
* when calling {@link JavaCompiler#getTask}. The "standard"
* options, such as {@code --class-path}, {@code --module-path},
* and so on are available when using the default file manager,
* or one derived from it. These options may not be available
* and different options may be available, when using a different
* file manager.
* {@link IllegalArgumentException} will be thrown if any option
* that is unknown to the tool or the file manager is used when
* invoking the tool through this API.
*
*
* Note that the {@code CLASSPATH} environment variable is honored
* when invoking the compiler through its API, although such use is discouraged.
* An environment variable cannot be unset once a VM has been started,
* and so it is recommended to ensure that the environment variable is not set
* when starting a VM that will be used to invoke the compiler.
* However, if a value has been set, any such value can be overridden by
* using the {@code --class-path} option when invoking the compiler,
* or setting {@link StandardLocation#CLASS_PATH} in the file manager
* when invoking the compiler through the {@link JavaCompiler} interface.
*
* SuppressWarnings
*
* JLS {@jls 9.6.4.5} specifies a number of strings that can be used to
* suppress warnings that may be generated by a Java compiler.
*
* In addition, javac also supports other strings that can be used
* to suppress other kinds of warnings. The following table lists all the
* strings that can be used with {@code @SuppressWarnings}.
*
*
* Strings supported by {@code SuppressWarnings}
*
* String Suppress Warnings About ...
* {@code auxiliaryclass} an auxiliary class that is hidden in a source file, and is used
* from other files
* {@code cast} use of unnecessary casts
* {@code classfile} issues related to classfile contents
* {@code deprecation} use of deprecated items
* {@code dep-ann} items marked as deprecated in a documentation comment but not
* using the {@code @Deprecated} annotation
* {@code divzero} division by constant integer {@code 0}
* {@code empty} empty statement after {@code if}
* {@code exports} issues regarding module exports
* {@code fallthrough} falling through from one case of a {@code switch} statement to
* the next
* {@code finally} {@code finally} clauses that do not terminate normally
* {@code lossy-conversions} possible lossy conversions in compound assignment
* {@code missing-explicit-ctor} missing explicit constructors in public and protected classes
* in exported packages
* {@code module} module system related issues
* {@code opens} issues regarding module opens
* {@code overloads} issues regarding method overloads
* {@code overrides} issues regarding method overrides
* {@code path} invalid path elements on the command line
* {@code preview} use of preview language features
* {@code rawtypes} use of raw types
* {@code removal} use of API that has been marked for removal
* {@code requires-automatic} use of automatic modules in the {@code requires} clauses
* {@code requires-transitive-automatic} automatic modules in {@code requires transitive}
* {@code serial} {@link java.base/java.io.Serializable Serializable} classes
* that do not have a {@code serialVersionUID} field, or other
* suspect declarations in {@code Serializable} and
* {@link java.base/java.io.Externalizable Externalizable} classes
* and interfaces
* {@code static} accessing a static member using an instance
* {@code strictfp} unnecessary use of the {@code strictfp} modifier
* {@code synchronization} synchronization attempts on instances of value-based classes
* {@code text-blocks} inconsistent white space characters in text block indentation
* {@code this-escape} superclass constructor leaking {@code this} before subclass initialized
* {@code try} issues relating to use of {@code try} blocks
* (that is, try-with-resources)
* {@code unchecked} unchecked operations
* {@code varargs} potentially unsafe vararg methods
* {@code doclint:accessibility} accessibility issues found in documentation comments
* {@code doclint:all} all issues found in documentation comments
* {@code doclint:html} HTML issues found in documentation comments
* {@code doclint:missing} missing items in documentation comments
* {@code doclint:reference} reference issues found in documentation comments
* {@code doclint:syntax} syntax issues found in documentation comments
*

* @toolGuide javac
*
* @provides java.util.spi.ToolProvider
