Chapter 11. Managing Service Registry content using the Maven plug-in
This chapter explains how to manage artifacts stored in the registry using the Service Registry Maven plug-in:
Prerequisites
- See Chapter 1, Introduction to Service Registry
- Service Registry must be installed and running in your environment
- Maven must be installed and configured in your environment
11.1. Managing artifacts using the Service Registry Maven plug-in
You can use the Service Registry Maven plug-in to upload or download registry artifacts as part of your development build. For example, this plug-in is useful for testing and validating that your schema updates are compatible with client applications.
Registering an artifact using the Maven plug-in
Probably the most common use case for the Maven plug-in is registering artifacts during a build. You can accomplish this by using the register execution goal.
Procedure
Update your Maven
pom.xmlfile to use theapicurio-registry-maven-pluginto register an artifact. The following example shows registering an Apache Avro schema:<plugin> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-maven-plugin</artifactId> <version>${registry.version}</version> <executions> <execution> <phase>generate-sources</phase> <goals> <goal>register</goal> 1 </goals> <configuration> <registryUrl>http://my-cluster-service-registry-myproject.example.com/api</registryUrl> 2 <artifactType>AVRO</artifactType> <artifacts> <schema1>${project.basedir}/schemas/schema1.avsc</schema1> 3 </artifacts> </configuration> </execution> </executions> </plugin>
Downloading an artifact using the Maven plug-in
You can also use the Maven plug-in to download artifacts from Service Registry. This is often useful, for example, when generating code from a registered schema.
Procedure
Update your Maven
pom.xmlfile to use theapicurio-registry-maven-pluginto download an artifact. The following example shows downloading a single schema by its artifact ID.<plugin> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-maven-plugin</artifactId> <version>${registry.version}</version> <executions> <execution> <phase>generate-sources</phase> <goals> <goal>download</goal> 1 </goals> <configuration> <registryUrl>http://my-cluster-service-registry-myproject.example.com/api</registryUrl> 2 <ids> <param1>schema1</param1> 3 </ids> <artifactExtension>.avsc</artifactExtension> 4 <outputDirectory>${project.build.directory}</outputDirectory> </configuration> </execution> </executions> </plugin>- 1
- Specify
downloadas the execution goal. - 2
- You must specify the Service Registry URL with the
/apiendpoint. - 3
- You can download multiple artifacts to a specified directory using the artifact ID.
- 4
- The plug-in automatically tries to select an appropriate file extension, but you can override it using
<artifactExtension>.
Testing an artifact using the Maven plug-in
You might want to verify that an artifact can be registered without actually making any changes. This is most often useful when rules are configured in Service Registry. Testing the artifact results in a failure if the artifact content violates any of the configured rules.
Even if the artifact passes the test, no content is added to Service Registry.
Procedure
Update your Maven
pom.xmlfile to use theapicurio-registry-maven-pluginto test an artifact. The following example shows testing an Apache Avro schema:<plugin> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-maven-plugin</artifactId> <version>${registry.version}</version> <executions> <execution> <phase>generate-sources</phase> <goals> <goal>test-update</goal> 1 </goals> <configuration> <registryUrl>http://my-cluster-service-registry-myproject.example.com/api</registryUrl> 2 <artifactType>AVRO</artifactType> <artifacts> <schema1>${project.basedir}/schemas/schema1.avsc</schema1> 3 </artifacts> </configuration> </execution> </executions> </plugin>
