.TH ECJ "1" "May 2013" 
.SH NAME
ecj \- manual page for eclipse JDT Compiler
.SH SYNOPSIS
.B ecj <options> <source files>\fR
.SH DESCRIPTION
The JDT Compiler (jdtc) is a command version of Java compiler for eclipse. ecj 
has basic java compiler options like SUN's javac.
.SH OPTIONS
.TP 20
\fB\-help\fR
display a help message
.TP
\fB\-version\fR
compiler version number
.SS Classpath options:
.br
.TP 20
\fB\-cp \-classpath\fR <directories and ZIP archives separated by :>
specify location for application classes and sources. Each directory or file can specify access rules for types between '[' and ']' (e.g. [-X] to forbid access to type X, [~X] to discourage access to type X, [+p/X:-p/*] to forbid access to all types in package p but allow access to p/X)
.TP
\fB\-bootclasspath\fR <directories and ZIP archives separated by :>
specify location for system classes. Each directory or file can specify access rules for types between '[' and ']'
.TP
\fB\-sourcepath\fR <directories and ZIP archives separated by :>
specify location for application sources. Each directory or file can specify access rules for types between '[' and ']'. Each directory can further specify a specific destination directory using a '-d' option between '[' and ']'; this overrides the general '-d' option.
.br
\[char46]class files created from source files contained in a jar file are put in the user.dir folder in case no general '-d' option is specified. ZIP archives cannot override the general '-d' option
.TP
\fB\-extdirs\fR <directories separated by :>
specify location for extension ZIP archives
.TP
\fB\-endoreseddirs\fR <directories separated by :>
specify location for endorsed ZIP archives
.TP
\fB\-d\fR <dir>
destination directory (if omitted no package directory structure is created); this option can be overridden per source directory
.TP
\fB\-d\fR none
generate no .class files
.TP
\fB\-encoding <enc>\fR
specify default encoding for all source files. Each file/directory can override it when suffixed with '['<enc>']' (e.g. X.java[utf8]).
.br
If multiple default encodings are specified, the last one will be used.
.SS Compliance options:
.TP 20
\fB\-1.3\fR
use 1.3 compliance (-source 1.3 -target 1.1)
.TP
\fB\-1.4\fR
use 1.4 compliance (-source 1.3 -target 1.2) (default)
.TP
\fB\-1.5 \-5 \-5.0\fR
use 1.5 compliance (-source 1.5 -target 1.5)
.TP
\fB\-1.6 \-6 \-6.0\fR
use 1.6 compliance (-source 1.6 -target 1.6)
.TP
\fB\-1.7 \-7 \-7.0\fR
use 1.7 compliance (-source 1.7 -target 1.7)
.TP
\fB\-source\fR <version>
set source level: 1.3 to 1.7 (or 5, 5.0, etc)
.TP
\fB\-target\fR <version>
set classfile target: 1.1 to 1.7 (or 5, 5.0, etc)
.br
cldc1.1 can also be used to generate the StackMap attribute
.SS Warning options:
.TP 20
\fB\-deprecation
deprecation outside deprecated code (equivalent to '-warn:+deprecation', default)
.TP
\fB\-nowarn -warn:none\fR
disable all warnings
.TP
\fB-nowarn:[<directories separated by :>]\fR
specify directories from which optional problems should be ignored
.TP
\fB\-?:warn -help:warn\fR
display advanced warning options
.SS Error options:
.TP
\fB\-err:<warnings separated by ,>
convert exactly the listed warnings to be reported as errors
.TP
\fB\-err:+<warnings separated by ,>
enable additional warnings to be reported as errors
.TP
\fB\-err:-<warnings separated by ,>
disable specific warnings to be reported as errors
.SS Setting warning or error options using properties file:
.TP 20
\fB\-properties <file>
set warnings/errors option based on the properties file contents. This option can be used with -nowarn, -err:.. or -warn:.. options, but the last one on the command line sets the options to be used.
.SS Debug options:
.TP 20
\fB\-g[:lines,vars,source]\fR
