Error building StructuredDataProfiler

[Floris Cornel]

Hey, I'm new to the Web Data Commons but very enthusiastic! 

I am trying to convert some of the Schema.org data to json, but I'm getting errors when trying to build the StructuredDataProfiler with oracle-java8 and maven, specifically about de.dwslab.dwslib.framework.Processor

[ERROR] /home/user/commonwebdata/trunk/src/main/java/org/webdatacommons/structureddata/stats/WDCQuadConverter.java:[67,8] constructor Processor in class de.dwslab.dwslib.framework.Processor<E> cannot be applied to given types;

  required: int

  found: no arguments

  reason: actual and formal argument lists differ in length

[ERROR] /home/user/commonwebdata/trunk/src/main/java/org/webdatacommons/structureddata/util/QuadSorter.java:[73,9] method does not override or implement a method from a supertype

Any idea's on how to fix this?

Hello,

it sounds like a java version compilation issue.

Are you sure you are compiling with java8 and which maven version are you using?

Best,

Anna

Hi,

Thank for your quick reply.

This is my output voor mvn -v:

Apache Maven 3.3.9

Maven home: /usr/share/maven

Java version: 1.8.0_161, vendor: Oracle Corporation

Java home: /usr/lib/jvm/java-8-oracle/jre

Default locale: en_US, platform encoding: UTF-8

I followed the http://webdatacommons.org/framework/index.html#toc2 for installation instructions (oracle-java8-installer from the ppa:webupd8team/java repository on ubuntu)

Hello,

the problem lies on the dwlab.dwlib dependency.

Could you please get the updated version of the library found here: https://github.com/dwslab/dwslib ? 

Best,

Anna
