| 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> | |||
| <p>Note: Ant uses only the names of the source and class files to find | |||
| the classes that need a rebuild. It will not scan the source and therefor | |||
| the classes that need a rebuild. It will not scan the source and therefore | |||
| will have no knowledge about nested classes, classes that are named different | |||
| from the source file and so on.</p> | |||
| <p>The directory structure of the source tree should follow the package | |||
| 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 | |||
| hierarchy.</p> | |||
| <p>It is possible to refine the set of files that are being compiled/copied. | |||
| This can be done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i> | |||
| attributes. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to | |||
| have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify | |||
| the files you want to have excluded. This is also done with patterns. And | |||
| finally with the <i>defaultexcludes</i> 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> | |||

| This can be done with the <code>includes</code>, <code>includesfile</code>, | |||
| <code>excludes</code>, <code>excludesfile</code>, | |||

| 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 | |||
| in the <code>srcdir</code> attribute or nested <src> element, or by using | |||
| wildcard patterns. See the section on | |||

| 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 | |||

| Jikes supports some extra options, which can be set be defining | |||
| properties prior to invoking the task. 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 "true" or "yes" to be | |||
| interpreted as anything other than false; by default | |||
