Troubleshooting Service Builder Blob Compile Issues

Issue

• Service builder with Blob and compound primary key throws compilation error.
• The console errors might look like this:

  [javac] /Users/xxxx-yyyy/Projects/aaaa/dxp/plugins-sdk/portlets/bbbbb-services-portlet/docroot/WEB-INF/service/com/aaaa/portal/model/InvoicePDFBlobModel.java:42: error: cannot find symbol 
  [javac] public InvoicePK getInvoiceId() { 
  [javac] ^ 
  [javac] symbol: class InvoicePK 
  [javac] location: class InvoicePDFBlobModel
      

Environment

• Liferay Blade
• Liferay Developer Studio
• Gradle 
• Any other Liferay IDE environment

Resolution

• The issue is that the dependencies are not current. For example, a sample project might have this snippet:

  buildscript {
  dependencies
  
  { classpath group: "com.liferay", name: "com.liferay.gradle.plugins", version: "3.13.26" }
  repositories {
  maven
  
  { url "https://repository-cdn.liferay.com/nexus/content/groups/public" }
  }
  }
  

• The dependency version is 3.13.26. If this is changed manually to 3.13.50, then using this version also includes server builder changes.

Once the dependency version number has been updated, the compilation error should be resolved and the module is built successfully. If this still does not resolve the issue, verify all other dependencies in other projects have also been updated.
