Rmic Task

## Rmic

### Description

Runs the rmic compiler for a certain class.

Rmic 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 _Stub nor _Skel classes). If you want to rmic a single class and this class is a class nested into another class, you have to specify the classname in the form `Outer$$Inner` instead of `Outer.Inner`.

It is possible to refine the set of files that are being rmiced. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks, on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of `<fileset>` (`dir` becomes `base`) as well as the nested `<include>`, `<exclude>` and `<patternset>` elements.

It is possible to use different compilers. This can be selected with the "build.rmic" property or the `compiler` attribute. There are three choices:

- sun (the standard compiler of the JDK)
- kaffe (the standard compiler of Kaffe)
- weblogic

The miniRMI project contains a compiler implementation for this task as well, please consult miniRMI's documentation to learn how to use it.

### Parameters

Attribute | Description | Required
base | the location to store the compiled files. | Yes
classname | the class for which to run `rmic`. | No
filtering | indicates whether token filtering should take place | No
sourcebase | Pass the "-keepgenerated" flag to rmic and move the generated source file to the given sourcebase directory. | No
stubversion | Specify the JDK version for the generated stub code. Specify "1.1" to pass the "-v1.1" option to rmic. | No
classpath | The classpath to use during compilation | No
classpathref | The classpath to use during compilation, given as reference to a PATH defined elsewhere | No
includes | comma- or space-separated list of patterns of files that must be included. All files are included when omitted. | No
includesfile | the name of a file. Each line of this file is taken to be an include pattern | No
excludes | comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. | No
excludesfile | the name of a file. Each line of this file is taken to be an exclude pattern | No
defaultexcludes | indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted. | No
verify | check that classes implement Remote before handing them to rmic (default is false) | No
iiop | indicates that portable (RMI/IIOP) stubs should be generated | No
iiopopts | additional arguments for IIOP class generation | No
idl | indicates that IDL output files should be generated | No
idlopts | additional arguments for IDL file generation | No
debug | generate debug info (passes -g to rmic). Defaults to false. | No
includeAntRuntime | whether to include the Ant run-time libraries; defaults to `yes`. | No
includeJavaRuntime | whether to include the default run-time libraries from the executing VM; defaults to `no`. | No
extdirs | location of installed extensions. | No
compiler | The compiler implementation to use. If this attribute is not set, the value of the `build.rmic` property, if set, will be used. Otherwise, the default compiler for the current VM will be used. (See the above list of valid compilers.) | No

### Parameters specified as nested elements

#### classpath and extdirs

`Rmic`'s classpath and extdirs attributes are PATH like structure and can also be set via a nested classpath and extdirs elements.

#### compilerarg

You can specify additional command line arguments for the compiler with nested `<compilerarg>` elements. These elements are specified like Command-line Arguments but have an additional attribute that can be used to enable arguments only if a given compiler implementation will be used.

Attribute | Description | Required
value | See Command-line Arguments. | Exactly one of these.
line
file
path
compiler | Only pass the specified argument if the chosen compiler implementation matches the value of this attribute. Legal values are the same as those in the above list of valid compilers.) | No

### Examples

      <rmic classname="com.xyz.FooBar" base="${build}/classes"/>

runs the rmic compiler for the class `com.xyz.FooBar`. The compiled files will be stored in the directory `${build}/classes`.

      <rmic base="${build}/classes" includes="**/Remote*.class"/>

runs the rmic compiler for all classes with `.class` files below `${build}/classes` whose classname starts with Remote. The compiled files will be stored in the directory `${build}/classes`.
