| <h2><a name="sysclasspath">build.sysclasspath</a></h2> |
| <p>The value of the build.sysclasspath property |
| controls how the system classpath, i.e. the classpath in effect when |
| Apache Ant is run, affects the behavior of classpaths in Ant. |
| The default behavior varies from task to task.</p> |
| |
| The values and their meanings are: |
| |
| <table cellspacing="20"> |
| <tr><th>value</th><th>meaning</th></tr> |
| <tr> |
| <td align="left" valign="top">only</td> |
| <td>Only the system classpath is used and classpaths specified in build files, |
| etc are ignored. This situation could be considered as the person running |
| the build file knows more about the environment than the person writing the |
| build file. |
| </td> |
| </tr> |
| |
| <tr> |
| <td align="left" valign="top">ignore</td> |
| <td> |
| The system classpath is ignored. This situation is the reverse of the |
| above. The person running the build trusts the build file writer to get the |
| build file right. This mode is recommended for portable scripts. |
| </td> |
| </tr> |
| |
| <tr> |
| <td align="left" valign="top">last</td> |
| <td> |
| The classpath is concatenated to any specified classpaths at the end. This |
| is a compromise, where the build file writer has priority. |
| </td> |
| </tr> |
| |
| <tr> |
| <td align="left" valign="top">first</td> |
| <td> |
| Any specified classpaths are concatenated to the system classpath. This is |
| the other form of compromise where the build runner has priority. |
| </td> |
| </tr> |
| </table> |
| |
| <p><em>Since Ant 1.7</em> the value of this property also affects the |
| bootclasspath settings--it combines the bootclasspath that has been |
| specified for a task with the bootclasspath of the Java VM running |
| Ant. If the property has not been set, it defaults to "ignore" in |
| this case.</p> |
