<h2 id="rmic">Rmic</h2>
<h3>Description</h3>
<p>Runs the <kbd>rmic</kbd> compiler for a certain class.</p>
<p><code>Rmic</code> can be run on a single class (as specified with the classname attribute) or a
number of classes at once (all classes below base that are neither <code>_Stub</code>
nor <code>_Skel</code> classes).  If you want to <code>rmic</code> a single class and this class is
a class nested into another class, you have to specify the classname in the
form <code>Outer$$Inner</code> instead of <code>Outer.Inner</code>.</p>
<p>It is possible to refine the set of files that are being <code>rmic</code>ed. This can be done
with the <var>includes</var>, <var>includesfile</var>, <var>excludes</var>, <var>excludesfile</var>
and <var>defaultexcludes</var> attributes. With the <var>includes</var> or <var>includesfile</var>
attribute you specify the files you want to have included by using patterns. The <var>exclude</var>
or <var>excludesfile</var> attribute is used to specify the files you want to have excluded. This is
also done with patterns. And finally with the <var>defaultexcludes</var> attribute, you can specify
whether you want to use default exclusions or not. See the section
on <a href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../Types/fileset.html">FileSet</a> and supports most
attributes of <code>&lt;fileset&gt;</code> (<var>dir</var> becomes <var>base</var>) as well as the
nested <code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code>
and <code>&lt;patternset&gt;</code> elements.</p>
<p id="compilervalues">It is possible to use different compilers. This can be selected with
the <code>build.rmic</code> property, the <var>compiler</var> attribute, or a nested element. Here
are the choices:</p>
<ul>
  <li><q>default</q>&mdash;the default compiler (<q>kaffe</q>, <q>sun</q> or <q>forking</q>) for the
    platform.
  <li><q>sun</q>&mdash;the standard compiler prior to JDK 9</li>
  <li><q>kaffe</q>&mdash;the standard compiler of <a href="https://github.com/kaffe/kaffe"
    target="_top">Kaffe</a></li>
  <li><q>weblogic</q></li>
  <li><q>forking</q>&mdash;(<em>since Apache Ant 1.7</em>) the <q>sun</q> compiler forked into a
    separate process.  <em>Since Ant 1.9.8</em>, this is the default when running on JDK 9+.</li>
  <li><q>xnew</q>&mdash;(<em>since Ant 1.7</em>) the <q>sun</q> compiler forked into a separate
    process, with the <kbd>-Xnew</kbd> option. This is the most reliable way to
    use <kbd>-Xnew</kbd>.<br/>JDK 9 has removed support for <kbd>-Xnew</kbd> and <em>since Ant
    1.9.8</em> this option will be rejected when running on JDK 9+.</li>
  <li><q></q> (empty string). This has the same behaviour as not setting the compiler attribute.
    First the value of <code>build.rmic</code> is used if defined, and if not, the default for the
    platform is chosen. If <code>build.rmic</code> is set to this, you get the default.</li>
</ul>

<p>The <a href="https://web.archive.org/web/20131225023602/http://dione.zcu.cz/~toman40/miniRMI/"
target="_top">miniRMI</a> project contains a compiler implementation for this task as well, please
consult miniRMI's documentation to learn how to use it.</p>

<h4>CORBA support</h4>

<p>Java 11 <a href="https://openjdk.java.net/jeps/320" target="_top">removes</a> the Java EE and
CORBA packages and <kbd>rmic</kbd> no longer supports either <kbd>-iiop</kbd>
or <kbd>-idl</kbd> options. Starting with Ant 1.10.3, the <kbd>rmic</kbd> task will fail when using
either while running Java 11+ unless you fork the task and explicitly specify an executable.</p>

<h3>Parameters specified as nested elements</h3>
<h4>classpath and extdirs</h4>
<p><code>Rmic</code>'s <var>classpath</var> and <var>extdirs</var> attributes
are <a href="../using.html#path">path-like structure</a> and can also be set via a nested
<code>classpath</code> and <code>extdirs</code> elements.</p>

<h4>compilerarg</h4>

<p>You can specify additional command line arguments for the compiler with
nested <code>&lt;compilerarg&gt;</code> elements.  These elements are specified
like <a href="../using.html#arg">Command-line Arguments</a> but have an additional attribute that
can be used to enable arguments only if a given compiler implementation will be used.</p>

  </tr>
</table>

<h4>compilerclasspath</h4>
<p><em>Since Ant 1.8.0</em></p>
<p>A <a href="../using.html#path">path-like structure</a> holding the classpath to use when loading
the compiler implementation if a custom class has been specified.  Doesn't have any effect when
using one of the built-in compilers.</p>

<h4>Any nested element of a type that implements RmicAdapter</h4>
<p><em>Since Ant 1.8.0</em></p>
<p>If a defined type implements the <code>RmicAdapter</code> interface a nested element of that type
can be used as an alternative to the <var>compiler</var> attribute.</p>

<h3>Examples</h3>

<p>Run the <kbd>rmic</kbd> compiler for the class <code>com.xyz.FooBar</code>. The compiled files
will be stored in the directory <samp>${build}/classes</samp>.</p>
<pre>&lt;rmic classname=&quot;com.xyz.FooBar&quot; base=&quot;${build}/classes&quot;/&gt;</pre>

<p>Run the <kbd>rmic</kbd> compiler for all classes with <samp>.class</samp> files
below <samp>${build}/classes</samp> whose classname starts with <code>Remote</code>. The compiled
files will be stored in the directory <samp>${build}/classes</samp>.</p>
<pre>&lt;rmic base=&quot;${build}/classes&quot; includes=&quot;**/Remote*.class&quot;/&gt;</pre>

<p>If you want to use a custom RmicAdapter <code>org.example.MyAdapter</code> you can either use
the <var>compiler</var> attribute:</p>
<pre>
&lt;rmic classname=&quot;com.xyz.FooBar&quot;
      base=&quot;${build}/classes&quot;
      compiler="org.example.MyAdapter"/&gt;</pre>
<p>or a define a type and nest this into the task like in:</p>
<pre>
&lt;componentdef classname="org.example.MyAdapter"
              name="myadapter"/&gt;
&lt;rmic classname=&quot;com.xyz.FooBar&quot;
      base=&quot;${build}/classes&quot;&gt;
  &lt;myadapter/&gt;
&lt;/rmic&gt;</pre>
<p>in which case your compiler adapter can support attributes and nested elements of its own.</p>
