Important information: Service Builder solution won't be available in Liferay Workspace until a new version of it will be released.

You can manually apply latest available Service Builder module version with following steps:

1. Go to https://mvnrepository.com/artifact/com.liferay/com.liferay.portal.tools.service.builder and take last released version number. For example, today last released version is: 1.0.309
2. Go to Liferay Workspace root folder
3. Add following line to gradle.properties file:

   com.liferay.portal.tools.service.builder.version=1.0.309

   (replace 1.0.309 with version number obtained from maven central page)

Steps to reproduce

1. Create a Liferay Workspace for Liferay 7.1 or 7.0 with a service builder project, for example with blade:
   • blade init -v 7.1
   • blade create test -t service-builder
2. Note: in order to test LPS solution, follow the steps explained above to edit gradle.properties file, so latest service builder version is applied to Liferay workspace
3. Configure a service builder entity with following service.xml

   <service-builder  package-path="test">
   	<namespace>FOO</namespace>
   	<entity local-service="true" name="Foo" remote-service="true" uuid="true">
   		<column name="id" primary="true" type="long" />
   		<column name="foo" type="long" />
   	</entity>
   </service-builder>

4. Execute gradlew buildService
5. Execute gradlew deploy
   • Expected behavior: generated code is compiled successfully
   • Wrong behavior: following compile error is produced
