How to import 2 different certificates with maven

I need to import two different certificates in my build process. I'm using keytool-maven-plugin, I'm able to import 1 plugin but I'm not able to import 2 different ones.

Here is my pom snippet

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>keytool-maven-plugin</artifactId>
    <version>1.5</version>
    <executions>
        <execution>
            <goals>
                <goal>importCertificate</goal>
            </goals>
            <phase>package</phase>
        </execution>
    </executions>
    <configuration>
        <keystore>${project.build.directory}/client-truststore.jks</keystore>
        <storepass>storepass</storepass>
        <alias>alias</alias>
        <file>ca.pem</file>
        <noprompt>true</noprompt>
    </configuration>
</plugin>

Thanks in advance.

Solution

Few things -

as discussed and inferred above <id> is something that you are missing in your <execution> tag
also, if you want to make the alias configurable please use changeAlias in your execution as -
```
<goals>
    <goal>changeAlias</goal>
</goals>
```

How to use keytool:changeAlias specifying parameters on the command line

> mvn keytool:changeAlias -Dkeystore=/path/to/your/keystore
> -Dstorepass=storepass -Dkeypass=keypass -Dalias=foo_alias \  -Ddestalias=new_alias

and for different executions you can try to configure different aliases as follows -

<executions>
   <execution>
       <goals>
         <goal>importCertificate</goal>
       </goals>
       <phase>package</phase>
       <id>executionOne</id>
       <configuration>
         <keystore>${project.build.directory}/client-truststore.jks</keystore>
         <storepass>storepass</storepass>
         <alias>alias</alias>
         <file>ca.pem</file>
         <noprompt>true</noprompt>
       </configuration>
   </execution>
   <execution>
       <goals>
         <goal>importCertificate</goal>
       </goals>
       <phase>package</phase>
       <id>executionTwo</id>
       <!--change this from one above-->
       <configuration>
         <keystore>${project.build.directory}/client-truststore.jks</keystore>
         <storepass>storepass</storepass>
         <alias>alias</alias>
         <file>ca.pem</file>
         <noprompt>true</noprompt>
       </configuration>
   </execution>
</executions>
