HOw to use jsonschema2pojo in maven's POM

Question

I have a JSON File and I want to convert it to POJO, for this I am using the plugin of org.jsonschema2pojo in maven. I am not able to generate the resultant pojo.Here's the snippet from pom.xml

<build>
                <plugins>
                    <plugin>


                        <groupId>org.jsonschema2pojo</groupId>
                        <artifactId>jsonschema2pojo-maven-plugin</artifactId>
                        <version>0.4.23</version>
                        <configuration>
                            <sourceDirectory>${basedir}/src/main/resources/schema</sourceDirectory>
                            <targetPackage>${basedir}/src/main/resources/result</targetPackage>
                        </configuration>
                        <executions>
                            <execution>
                                <goals>
                                    <goal>generate</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>

I am using the generate sources goal in maven. My expectation is that it should give me pojo files at ${basedir}/src/main/resources/result location. However I am getting so. Please help me out. Thanks, Rajit

Answer 1

You want to use <outputDirectory> instead of <targetPackage>. More details here:

• http://joelittlejohn.github.io/jsonschema2pojo/site/0.4.23/generate-mojo.html#outputDirectory

• http://joelittlejohn.github.io/jsonschema2pojo/site/0.4.23/generate-mojo.html#targetPackage

Target package is the Java package you want your types to use, e.g. com.youcompany.model.

Also, typically you want the generated output to go into the target directory, not src. Derived files usually go there since anything inside target is usually omitted from source control. You don't need to specify outputDirectory if you don't want to, by default the generated output will go into /target/java-gen.

Thnks for the reply. I have removed the line" <targetPackage>${basedir}/src/main/resources/result</targetPackage>" but still the files are not getting generated in the target folder. Now my configuration file is <configuration> <sourceDirectory>${basedir}/src/main/resources/schema/jsonSample.json</sourceDirectory> </configuration> Note: Iam using generate-sources phase of maven to build. My target folder now contains only maven-status folder. Please suggest. – Expugnable

If you are generating code from JSON (not from JSON schema), use <sourceType>json</sourceType> in your jsonschema2pojo plugin configuration. – Mole

Below code works for me.

<plugin>
    <groupId>org.jsonschema2pojo</groupId>
    <artifactId>jsonschema2pojo-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>1</id>
            <configuration>
                <annotationStyle>jackson2</annotationStyle>
                <includeAdditionalProperties>false</includeAdditionalProperties>
                <sourcePaths>
                    <sourcePath>${project.basedir}/src/main/resource/jsd/your_schema.json</sourcePath>
                </sourcePaths>
                <targetPackage>your target package</targetPackage>
            </configuration>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
        <execution>
            <id>2</id>
            <configuration>
                <annotationStyle>jackson2</annotationStyle>
                <includeAdditionalProperties>false</includeAdditionalProperties>
                <sourcePaths>
                    <sourcePath>${project.basedir}/src/main/resource/jsd/your_schema2.json</sourcePath>
                </sourcePaths>
                <targetPackage>your target package</targetPackage>
            </configuration>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Use both targetPackage and outputDirectory.

      <plugin>
        <groupId>org.jsonschema2pojo</groupId>
        <artifactId>jsonschema2pojo-maven-plugin</artifactId>
        <version>1.0.2</version>
        <configuration>
          <sourceDirectory>${basedir}/src/main/resources/schema</sourceDirectory>
          <outputDirectory>src/main/java</outputDirectory>
          <targetPackage>com.your.package</targetPackage>
        </configuration>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
