Can I use property file in maven pom.xml for flyway configuration

Question

<plugin>     <groupId>com.googlecode.flyway</groupId>     <artifactId>flyway-maven-plugin</artifactId>     <version>1.7</version>     <configuration>         <driver>com.mysql.jdbc.Driver</driver>         <url>jdbc:mysql://127.0.0.1:3306/db_abc</url>         <user>db_user</user>         <sqlMigrationPrefix>V</sqlMigrationPrefix>     </configuration> </plugin> 

I don't want to mention driver, url and user here. I already have a abc.property on src/main/resources. How can use that file here?

Answer 1

Have a look at the properties-maven-plugin. It allows you to read properties from a file to then use them in your pom.

Add the following plugin defintion:

  <plugin>     <groupId>org.codehaus.mojo</groupId>     <artifactId>properties-maven-plugin</artifactId>     <version>1.0.0</version>     <executions>       <execution>         <phase>initialize</phase>         <goals>           <goal>read-project-properties</goal>         </goals>         <configuration>           <files>             <file>src/main/resources/abc.properties</file>           </files>         </configuration>       </execution>     </executions>   </plugin> 

If abc.properties contains:

jdbc.driver = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://127.0.0.1:3306/db_ab jdbc.user = db_user 

You can then use the properties as follows:

<!-- language: xml -->  <driver>${jdbc.driver}</driver> <url>${jdbc.url}</url> <user>${jdbc.user}</user>
