| 28 | <h3>Description</h3>
|
|---|
| 29 | <p>This is a basic task that can be used to track build numbers.</p>
|
|---|
| 30 | <p>It will first attempt to read a build number from a file (by default,
|
|---|
| 31 | <code>build.number</code> in the current directory), then
|
|---|
| 32 | set the property <code>build.number</code> to the value that was read in
|
|---|
| 33 | (or to <code>0</code>, if no such value). It will then increment the
|
|---|
| 34 | number by one and write it back out to the file.
|
|---|
| 35 | (See the
|
|---|
| 36 | <a href="../OptionalTasks/propertyfile.html">PropertyFile</a> task
|
|---|
| 37 | if you need finer control over things such as the property name or
|
|---|
| 38 | the number format.)
