How to disable antrun if certain file already exists?
How can I disable maven-antrun-plugin execution when certain file already exists?:
[...]
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<!-- do something really complex in order to create file.txt -->
</target>
</configuration>

The execution takes some time and I don't want to repeat it every time when file.txt
is already there.
Check for the presence of the file in your standalone Ant file. Example:
<target name="check-file">
<available file="foo.bar" property="fileExists" />
</target>
<target name="time-consuming" depends="check-file" unless="fileExists">
...
</target>
Use a <profile>
that's only active if file.txt
doesn't exist:
<profiles>
<profile>
<id>createFile</id>
<activation><file><missing>file.txt</missing></file></activation>
<build><plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<!-- etc -->
</plugin>
</plugins></build>
</profile>
</profiles>
