Eclipse Null Pointer Exception when building project with generated jOOQ source

[sche...@gmail.com]

Hi there

I have an Eclipse Gradle project that uses jOOQ to generate source from a schema. 

I get a Null pointer exception when Eclipse tries to build (F5) my Java project.

The Gradle build is successful and the jOOQ source is successfully built and added to the classpath.

It is the Java build of some of the jOOQ generated code that is the problem I believe:

The full error is as follows:

eclipse.buildId=4.7.3.M20180330-0640

My gradle.build files is as follows:

  gradleVersion = '4.7'

}

ext {

  jooqVersion = "3.10.6"

  postgresVersion = "42.2.2"

}

apply plugin: 'java'

apply plugin: 'nu.studer.jooq'

sourceCompatibility = 1.10

targetCompatibility = 1.10

repositories {

  jcenter()

  mavenCentral()

 }

dependencies {

  

  compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.9.5'

  compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.9.5'

      }

      generate {

        relations = true

        deprecated = false

        records = true

        immutablePojos = true

        fluentSetters = true

      }

      target {

        packageName = "railyard.db"

      }

   }

  }

}

and my gradle.properties file is as follows:

org.gradle.jvmargs=--add-modules java.xml.bind

Any solutions for this?

Best,

Martin

Hi Martin,

This looks like an Eclipse problem much more than like a jOOQ problem, to me. Perhaps you could try reporting the issue to Eclipse instead

Thanks,

Lukas
