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>
