Topic: NPE Error running FHIR build
Jean Duteau (Nov 16 2020 at 19:47):
I'm trying to do a FHIR core build after being away for awhile. I keep getting a NullPointer when it is trying to produce schemas. To make sure it wasn't something I did, I just cloned a fresh repository and ran it and am getting the same error. I had Melva do a build on her machine and it got past this point:
[java] Generate RDF 0.458 50sec 1121MB
[java] Produce Schemas 2.605 53sec 592MB
[java] This was a Full Build 0.015 53sec 596MB

In the code at that spot, it's trying to output some code system:
write(" <xs:enumeration value=\"" + Utilities.escapeXml(cc.getCode()) + "\">\r\n");
write(" <xs:annotation>\r\n");
write(" <xs:documentation xml:lang=\"en\">" + Utilities.escapeXml(cc.getDisplay()) + "</xs:documentation>\r\n"); // todo: do we need to look the definition up?
CodeSystem cs = workerContext.fetchCodeSystem(cc.getSystem());
if (cs != null && cc.hasCode()) {
ConceptDefinitionComponent c = getCodeDefinition(cc.getCode(), cs.getConcept());
for (ConceptDefinitionDesignationComponent l : c.getDesignation())
if (l.hasLanguage())
write(" <xs:documentation xml:lang=\""+l.getLanguage()+"\">"+Utilities.escapeXml(l.getValue())+"</xs:documentation>\r\n");
}

adding some debug code and the error occurs when it's trying to write out http://unitsofmeasure.org#s
Jean Duteau (Nov 16 2020 at 20:04):
I added a null check around the for statement above as a workaround
Vassil Peytchev (Nov 16 2020 at 20:20):
Did you run clean before trying to build?
Jean Duteau (Nov 16 2020 at 20:23):
yep. and as I said, I also created a clean new repository clone
Grahame Grieve (Nov 16 2020 at 21:06):
http://unitsofmeasure.org#s ? or http://unitsofmeasure.org#vs
Jean Duteau (Nov 16 2020 at 21:07):
i spit out code system and code and that was spit out just before the NPE
Grahame Grieve (Nov 16 2020 at 21:23):
ah
Grahame Grieve (Nov 16 2020 at 22:25):
oh, this is a downstream consequence of UTG fake declarations...
Jean Duteau (Dec 21 2020 at 21:19):
I'm still getting this NPE when I try to build FHIR locally. I'm not sure why others aren't seeing this.
Jean Duteau (Dec 21 2020 at 21:26):
I had to add this line in XSDBaseGenerator to get around the NPE:
ConceptDefinitionComponent c = getCodeDefinition(cc.getCode(), cs.getConcept());
if (c != null)
for (ConceptDefinitionDesignationComponent l : c.getDesignation())
(line 559-560)
Grahame Grieve (Dec 23 2020 at 01:13):
what code does this trigger for>?
Grahame Grieve (Dec 23 2020 at 01:13):
because there's an underlying problem if this happens
Jean Duteau (Dec 23 2020 at 18:06):
I'm assuming the same one as before (http://unitsofmeasure.org#s) but I'll put my debugging code back in to double-check
