| |
| <h3>Description</h3> |
| |
| <p>Asserts a condition and makes the build fail (using a special |
| kind of BuildException) if it doesn't hold true.</p> |
| |
| <h3>Parameters</h3> |
| <table border="1" cellpadding="2" cellspacing="0"> |
| <tr> |
| <td valign="top"><b>Attribute</b></td> |
| <td valign="top"><b>Description</b></td> |
| <td align="center" valign="top"><b>Required</b></td> |
| </tr> |
| <tr> |
| <td valign="top">message</td> |

| </tr> |
| </table> |
| |
| <h3>Parameters specified as nested elements</h3> |
| <h4>exactly one supported condition</h4> |
| |
| <p>You can use all supported conditions of Ant's core as well as |
| any class that implements the Condition interface as a nested |
| child element. This element is required - exactly one child - and |
| specifies the condition to assert.</p> |
| |
| <h3>Examples</h3> |
| |
| <p>Make the build fail with the message "foo is bar" if the |
| property <code>foo</code> has the value bar:</p> |
| |
| <pre> |
| <assertTrue message="foo is bar"> |
| <not> |
| <equals arg1="${foo}" arg2="bar"/> |
| </not> |
| </assertTrue> |
| </pre> |
