NAME

SYNOPSIS

9       ant [OPTIONS] [TARGET [TARGET2 [TARGET3] ...]]
10

DESCRIPTION

12       Apache Ant is a Java library and command-line tool whose mission is to
13       drive processes described in build files as targets and extension
14       points dependent upon each other. The main known usage of Ant is the
15       build of Java applications. Ant supplies a number of built-in tasks
16       allowing to compile, assemble, test and run Java applications. Ant can
17       also be used effectively to build non Java applications, for instance C
18       or C++ applications. More generally, Ant can be used to pilot any type
19       of process which can be described in terms of targets and tasks.
20

USAGE

22       When no arguments are specified, Ant looks for a build.xml file in the
23       current directory and, if found, uses that file as the build file and
24       runs the target specified in the default attribute of the <project>
25       tag. To make Ant use a build file other than build.xml, use the
26       command-line option -buildfile file, where file is the name of the
27       build file you want to use (or a directory containing a build.xml
28       file).
29
30       If you use the -find [file] option, Ant will search for a build file
31       first in the current directory, then in the parent directory, and so
32       on, until either a build file is found or the root of the filesystem
33       has been reached. By default, it will look for a build file called
34       build.xml. To have it search for a build file other than build.xml,
35       specify a file argument. Note: If you include any other flags or
36       arguments on the command line after the -find flag, you must include
37       the file argument for the -find flag, even if the name of the build
38       file you want to find is build.xml.
39
40       You can also set properties on the command line. This can be done with
41       the -Dproperty=value option, where property is the name of the
42       property, and value is the value for that property. If you specify a
43       property that is also set in the build file (see the property task),
44       the value specified on the command line will override the value
45       specified in the build file. Defining properties on the command line
46       can also be used to pass in the value of environment variables; just
47       pass -DMYVAR=$MYVAR to Ant. You can then access environment variables
48       using the property task’s environment attribute.
49
50       Options that affect the amount of logging output by Ant are: -quiet,
51       which instructs Ant to print less information to the console; -verbose,
52       which causes Ant to print additional information to the console;
53       -debug, which causes Ant to print considerably more additional
54       information; and -silent which makes Ant print nothing but task output
55       and build failures (useful to capture Ant output by scripts).
56
57       It is also possible to specify one or more targets that should be
58       executed. When omitted, the target that is specified in the default
59       attribute of the project tag is used.
60
61       The -projecthelp option prints out a list of the build file’s targets.
62       Targets that include a description attribute are listed as "Main
63       targets", those without a description are listed as "Other targets",
64       then the "Default" target is listed ("Other targets" are only displayed
65       if there are no main targets, or if Ant is invoked in -verbose or
66       -debug mode).

EXAMPLES

147       ant
148           runs Ant using the build.xml file in the current directory, on the
149           default target.
150
151       ant -buildfile test.xml
152           runs Ant using the test.xml file in the current directory, on the
153           default target.
154
155       ant -buildfile test.xml dist
156           runs Ant using the test.xml file in the current directory, on the
157           target called dist.
158
159       ant -buildfile test.xml -Dbuild=build/classes dist
160           runs Ant using the test.xml file in the current directory, on the
161           target called dist, setting the build property to the value
162           "build/classes".
163
164       ant -lib /home/ant/extras
165           runs Ant picking up additional task and support jars from the
166           /home/ant/extras location
167
168       ant -lib one.jar;another.jar
169           adds two jars to Ants classpath.
170

FILES

172       The Ant wrapper script for Unix will source (read and evaluate) the
173       file ~/.antrc before it does anything. You can use the file, for
174       example, to set/unset environment variables that should only be visible
175       during the execution of Ant.
176

ENVIRONMENT VARIABLES

178       The wrapper scripts use the following environment variables (if set):
179
180       JAVACMD
181           full path of the Java executable. Use this to invoke a different
182           JVM than JAVA_HOME/bin/java.
183
184       ANT_OPTS
185           command-line arguments that should be passed to the JVM. For
186           example, you can define system properties or set the maximum Java
187           heap size here.
188
189       ANT_ARGS
190           Ant command-line arguments. For example, set ANT_ARGS to point to a
191           different logger, include a listener, and to include the -find
192           flag. Note: If you include -find in ANT_ARGS, you should include
193           the name of the build file to find, even if the file is called
194           build.xml.
