<h3>Description</h3>

2001-08-30 13:23:14 +00:00
|
|
|
<p>Compiles a Java source tree.</p>
|
2001-02-13 12:32:01 +00:00
|
|
|
<p>The source and destination directory will be recursively scanned for Java
|
2002-03-20 05:20:55 +00:00
|
|
|
source files to compile. Only Java files that have no corresponding
|
|
|
|
|
<code>.class</code> file
|
|
|
|
|
or where the class file is older than the
|
|
|
|
|
<code>.java</code> file will be compiled.</p>
|
2001-04-26 23:31:43 +00:00
|
|
|
<p>Note: Ant uses only the names of the source and class files to find
|
2002-03-20 05:20:55 +00:00
|
|
|
the classes that need a rebuild. It will not scan the source and therefore
|
2001-04-26 23:31:43 +00:00
|
|
|
will have no knowledge about nested classes, classes that are named different
|
2002-03-20 05:20:55 +00:00
|
|
|
from the source file, and so on. See the
|
|
|
|
|
<a href="../OptionalTasks/depend.html"><code><depend></code></a> task
|
|
|
|
|
for dependency checking based on other than just
|
|
|
|
|
existence/modification times.
|
|
|
|
|
<p>When the source files are part of a package, the directory structure of
|
|
|
|
|
the source tree should follow the package
|
2001-02-13 12:32:01 +00:00
|
|
|
hierarchy.</p>
|
2002-03-20 05:20:55 +00:00
|
|
|
<p>It is possible to refine the set of files that are being compiled.
|
|
|
|
|
This can be done with the <code>includes</code>, <code>includesfile</code>,
|
2002-03-20 05:24:06 +00:00
|
|
|
<code>excludes</code>, and <code>excludesfile</code>
|
2002-03-20 05:20:55 +00:00
|
|
|
attributes. With the <code>includes</code> or
|
|
|
|
|
<code>includesfile</code> attribute, you specify the files you want to
|
|
|
|
|
have included.
|
|
|
|
|
The <code>exclude</code> or <code>excludesfile</code> attribute is used
|
|
|
|
|
to specify
|
|
|
|
|
the files you want to have excluded. In both cases, the list of files
|
|
|
|
|
can be specified by either the filename, relative to the directory(s) specified
|
2002-03-20 05:27:43 +00:00
|
|
|
in the <code>srcdir</code> attribute or nested <code><src></code>
|
|
|
|
|
element(s), or by using wildcard patterns. See the section on
|
2002-03-20 05:20:55 +00:00
|
|
|
<a href="../dirtasks.html#directorybasedtasks">directory-based tasks</a>,
|
|
|
|
|
for information on how the
|
|
|
|
|
inclusion/exclusion of files works, and how to write wildcard patterns.</p>
|
|
|
|
|
<p>It is possible to use different compilers. This can be specified by
|
|
|
|
|
either setting the global <code>build.compiler</code> property, which will
|
|
|
|
|
affect all <code><javac></code> tasks throughout the build, or by
|
|
|
|
|
setting the <code>compiler</code> attribute, specific to the current
|
|
|
|
|
<code><javac></code> task.
|
|
|
|
|
<a name="compilervalues">Valid values for either the
|
|
|
|
|
<code>build.compiler</code> property or the <code>compiler</code>
|
|
|
|
|
attribute are:</p>

2002-03-20 05:20:55 +00:00
|
|
|
<li><code>classic</code> (the standard compiler of JDK 1.1/1.2) –
|
|
|
|
|
<code>javac1.1</code> and
|
|
|
|
|
<code>javac1.2</code> can be used as aliases.</li>
|
|
|
|
|
<li><code>modern</code> (the standard compiler of JDK 1.3/1.4) –
|
|
|
|
|
<code>javac1.3</code> and

|
|

|
<li><code>jvc</code> (the Command-Line Compiler from Microsoft's SDK
|

as an alias.</li>

<li><code>kjc</code> (the <a href="http://www.dms.at/kopi/" target="_top">kopi</a>

<li><code>gcj</code> (the gcj compiler from gcc).</li>
|
|

<li><code>sj</code> (Symantec java compiler) –

|
|
|
|
<code>symantec</code> can be used as an alias.</li>

|
<li><code>extJavac</code> (run either modern or classic in a JVM of
|
|
|
|
|
its own).</li>

2002-03-20 05:20:55 +00:00

</a>
|
|
|
|
|
<p>For JDK 1.1/1.2, <code>classic</code> is the default.
|
|

For JDK 1.3/1.4, <code>modern</code> is the default.

|
|
|
If you wish to use a different compiler interface than those
|
2002-03-20 05:20:55 +00:00
|
|
|
supplied, you can write a class that implements the CompilerAdapter interface
|
|
|
|
|
(<code>package org.apache.tools.ant.taskdefs.compilers</code>). Supply the full
|
|
|
|
|
classname in the <code>build.compiler</code> property or the
|
|
|
|
|
<code>compiler</code> attribute.
|
2001-02-13 12:32:01 +00:00
|
|
|
</p>
|
2002-03-20 05:20:55 +00:00
|
|
|
<p>The fork attribute overrides the <code>build.compiler</code> property
|
|
|
|
|
or <code>compiler</code> attribute setting and
|
|
|
|
|
expects a JDK1.1 or higher to be set in <code>JAVA_HOME</code>.
|
2001-08-03 14:36:48 +00:00
|
|
|
</p>
|
2001-12-26 20:35:14 +00:00
|
|
|
<p>This task will drop all entries that point to non-existent
|
2002-03-20 05:20:55 +00:00
|
|
|
files/directories from the classpath it passes to the compiler.</p>
|
2001-12-10 15:31:54 +00:00
|
|
|
<p><strong>Windows Note:</strong>When the modern compiler is used
|
|
|
|
|
in unforked mode on Windows, it locks up the files present in the
|
2002-03-20 05:20:55 +00:00
|
|
|
classpath of the <code><javac></code> task, and does not release them.
|
|
|
|
|
The side effect of this is that you will not be able to delete or move
|
2001-12-10 15:31:54 +00:00
|
|
|
those files later on in the build. The workaround is to fork when
|
|
|
|
|
invoking the compiler.</p>

If you wish to compile only source files located in certain packages below a

|
|
|
common root, use the <code>include</code>/<code>exclude</code> attributes
|
|
|
|
|
or <code><include></code>/<code><exclude></code> nested elements
|
|
|
|
|
to filter for these packages. Do not include part of your package structure
|
|
|
|
|
in the <code>srcdir</code> attribute
|
|
|
|
|
(or nested <code><src></code> elements), or Ant will recompile your
|
|
|
|
|
source files every time you run your compile target. See the
|
|
|
|

<a href="http://jakarta.apache.org/ant/faq.html#always-recompiles">Ant FAQ</a>

<p><b>Note:</b> If you are using Ant on Windows and a new DOS window pops up
|
|
|
|

for every use of an external compiler, this may be a problem of the JDK you are
|

|
using. This problem may occur with all JDKs < 1.2.</p>

<h3>Jikes Notes</h3>
|
|
|
|
|
|
2001-09-30 13:21:54 +00:00
|
|
|
Jikes supports some extra options, which can be set be defining
|
2002-03-20 05:20:55 +00:00
|
|
|
the properties shown below prior to invoking the task. The setting
|
|
|
|
|
for each property will be in affect for all <code><javac></code>
|
|
|
|
|
tasks throughout the build.
|
|
|
|
|
The Ant developers are aware that
|
|
|
|
|
this is ugly and inflexible – expect a better solution in the future.
|
|
|
|
|
All the options are boolean, and must be set to <code>true</code> or
|
|
|
|
|
<code>yes</code> to be
|
|
|
|
|
interpreted as anything other than false. By default,
|
|
|
|
|
<code>build.compiler.warnings</code> is <code>true</code>,
|
|
|
|
|
while all others are <code>false</code>.</p>
