25 | * <p>Input type to select targets to install </p>
|
---|
26 | * If the osSpecific flag is set the OS of the current system will
|
---|
27 | * be appended to the name of the target actually by ant run so that different
|
---|
28 | * Targets can be run according to the target platform.
|
---|
29 | * This feature goes against the principles of
|
---|
30 | * building cross platform installers, but is provided so that common installer
|
---|
31 | * tasks such as creating icons and shortcuts can be run on Windows for
|
---|
32 | * all those useless users who can't run a command script ;)
|
---|
33 | * <br>
|
---|
34 | * Currently there are two modes strict and not strict (lax).</p>
|
---|
35 | * <p>Strict target will return the target name plus the exact String in the
|
---|
36 | * System Property "os.name" this means you will have to provide targets for
|
---|
37 | * every possible OS version. See
|
---|
38 | * <a href="http://lopica.sourceforge.net/os.html">this page</a> for a list of possible values
|
---|
39 | * There are a great many but you may not want to consider some of the options.</p>
|
---|
40 | * <p>Lax target will return one of the following strings only
|
---|
41 | * <ul>
|
---|
42 | * <li>"[target-name]-linux" - Linux </li>
|
---|
43 | * <li>"[target-name]-mac" - Mac OS and Mac OS X</li>
|
---|
44 | * <li>"[target-name]-sun" - SunOS and Solaris</li>
|
---|
45 | * <li>"[target-name]-win" - Windows *</li>
|
---|
46 | * <li>"[target-name]-other" - any thing else</li>
|
---|
47 | * </ul></p> so you only have to create 5 ant targets to support all the cases.
