<HTML><HEAD><TITLE>Manpage of jikes</TITLE> </HEAD><BODY> <H1>jikes</H1> Section: User Commands (1) <A HREF="#index">Index</A> <A NAME="lbAB"> </A> <H2>NAME</H2> jikes - java source to bytecode compiler <A NAME="lbAC"> </A> <H2>SYNOPSIS</H2> jikes [-options] [+options] [@files]       file.java... Options, @files, and filenames may be intermixed. Individual options should not be repeated, unless noted below. <A NAME="lbAD"> </A> <H2>DESCRIPTION</H2> Jikes translates Java(TM) source files to bytecode. Features include strict adherence to the language specification, automatic makefile generation and incremental compilation. It is maintained by the Jikes Project. At this time, jikes only recognizes the full name of options; you cannot abbreviate or group them. You can give different argument types in any order. Options are global, so they affect compilation of files listed earlier on the command line. Duplicated options override the previous one, unless otherwise listed. If an option is listed in the form +T=n, it can also be specified as +T n or even +Tn. <A NAME="lbAE"> </A> <H2>OPTIONS</H2> Jikes may be invoked with the following command-line options: <DL COMPACT> <DT>-bootclasspath path<DD> <DT>--bootclasspath path<DD> Use path for the bootclasspath. This path is searched first for library class files, and is usually set to java/lib/classes.zip or java/jre/lib/rt.jar. This defaults to an empty path. <DT>-classpath path<DD> <DT>-cp path<DD> <DT>--classpath path<DD> Use path for CLASSPATH. This path is searched for both user source and compiled class files. This defaults to the current directory. <DT>-d directory<DD> <DT>--target-directory directory<DD> Write class files in the specified directory. Note that this directory is NOT in your classpath unless you list it there as well. This defaults to the current directory. <DT>-debug<DD> No effect (recognized for compatibility). <DT>-depend<DD> <DT>--depend<DD> <DT>-Xdepend<DD> Recompile all used classes. <DT>-deprecation<DD> <DT>--deprecation<DD> Report uses of deprecated features. <DT>-encoding encoding<DD> <DT>--encoding encoding<DD> Use specified encoding to read source files. This is not available in some builds, because it requires a working iconv or ICU encoder. Note that binary distributions for some platforms (such as Windows) do NOT include support for the encoding option, as there is not an adequate transcoding library available on all platforms by default. You can tell if a binary has encoding support or not by running jikes --help and looking for the --encoding option: if it is not listed, then this binary does NOT include support for encoding. This defaults to a platform-dependent encoding (such as ASCII). <DT>-extdirs path<DD> <DT>--extdirs path<DD> Use path for extensions directories. This is typically set to grab jar and zip extension files located in java/jre/lib/ext. This defaults to an empty path. <DT>-g<DD> Equivalent to -g:source,lines,vars. <DT>-g:none|{source,lines,vars}<DD> Specify which of three classfile debug options should be enabled. If this is not specified, the default is source,lines. source stores the filename of the source file in the class file, lines adds line number tracking to tie bytecodes to their location in the source file, and vars adds a table in the class file which stores the name of local variables and parameters, as well as their scope. This defaults to line and source information, but not vars. <DT>-help<DD> <DT>--help<DD> <DT>-h<DD> <DT>-?<DD> Prints a helpful summary of options, then exit. Overrides all other options, and nothing is compiled. <DT>-J...<DD> No effect, since jikes is native code, and does not need a Virtual Machine (ignored for compatibility). <DT>-nowarn<DD> <DT>--nowarn<DD> <DT>-q<DD> Do not issue warning messages. For greater control over warnings and cautions, see the +Z option. <DT>-nowrite<DD> <DT>--nowrite<DD> Do not write any class files, but list which ones would be written if used with -verbose. <DT>-O<DD> <DT>--optimize<DD> Optimize the bytecode. Technically, this means jikes should inline private and final methods where appropriate, but currently it does nothing. <DT>-source release<DD> <DT>--source release<DD> Specify which Java SDK release the source syntax obeys. For example, to treat the assert keyword as a normal identifier, you can use -source 1.3. Setting a lower target results in backward compatibility compilation of old source files. Valid releases are 1.3 (Java Language Specification, 2nd edition), and 1.4 (addition of the assert statement, JSR 41). Plans are underway to eventually support 1.5 (addition of generics: JSR 14; autoboxing, enhanced for-loop, static import, enums, and varargs: JSR 201; metadata: JSR 175; and updated .class file format: JSR 202; ultimately the Java Language Specification, 3rd edition). If not specified, this defaults to the valid value closest to the one specified or defaulted for -target (typically 1.4). <DT>-sourcepath path<DD> <DT>--sourcepath path<DD> Use path for specifying user "source only" directories. Class files in this path are ignored unless listed in other paths. This defaults to the empty path. <DT>-target release<DD> <DT>--target release<DD> Specify which Java SDK release the bytecode should target. For example, exception chaining was introduced in the 1.4 release, so a failed class literal can chain the NoClassDefFoundError to its original ClassNotFoundException; while the behavior in the 1.3 release simply discards the original exception. To get the old behavior, you can use -target 1.3. Setting a lower target results in forward compatibility to older virtual machines, and some source constructs will be compiled to less efficient workarounds in order to avoid known virtual machine bugs or deficiencies. However, a lower target may occaisionally produce incorrect semantic behavior. Furthermore, some language features require virtual machine support, where there are no known workarounds in earlier releases: the assert statement requires 1.4 (unless you also use -noassert), and the planned addition of typesafe enumerations will require 1.5. The planned addition of type parameterization (also known as generics) will work with 1.1. Valid releases are 1.1, 1.2, 1.3, 1.4, and 1.4.2; plans are underway to support 1.5. If not specified, this defaults to the value specified for -source, and if that is not specified, this defaults to 1.4.2. <DT>-verbose<DD> <DT>--verbose<DD> <DT>-v<DD> List files read and written. Also useful with -nowrite for a dry run to track dependencies. <DT>-version<DD> <DT>--version<DD> <DT>-V<DD> Print a version message, and contact information, then exit. Overrides all other options except --help, and nothing is compiled. <DT>-Werror<DD> Equivalent to +Z2, provided for javac compatibility. <DT>-Xstdout<DD> Write error messages to standard output, not stderr. At the moment, this is incompatible with javac, which takes an argument as the name of the file where it will direct compiler message output. <DT>-Xswitchcheck<DD> Synonym to +Pswitchcheck. Warns about fallthrough switch cases. <DT>++<DD> <DT>--incremental<DD> Compile in incremental mode. In this mode, jikes stays resident, and every keypress of Enter will trigger a recompilation of every source file rendered out-of-date by file modifications since the last co
