How do you use issueFunction with JqlClauseBuilder?

Question

I'm trying to build a JQL query using the JqlClauseBuilder that calls the "issueFieldExactMatch" function provided by script runner. Just wondering how to call this function, because I can't seem to work it out?

This was my first attempt:

JqlClauseBuilder builder = JqlQueryBuilder.newClauseBuilder();

Query query = builder.project(projectId).and().issueType().in(VALID_ISSUETYPES as Long[]).and().not().issue(issue.getKey()).and().field("issueFunction").inFunc("issueFieldExactMatch", "", "summary", currentSummary).buildQuery()

but it seems to generate the following jql (note the missing empty string in the "subquery" argument):

project = "10000" AND issuetype  in (10400,10401,10402,10403) AND issueFunction in issueFieldExactMatch(, summary, "Test")

What it should generate is:

project = "10000" AND issuetype  in (10400,10401,10402,10403) AND issueFunction in issueFieldExactMatch("", summary, "Test")

I've tried various escape methods but none of them have worked. The closest I've come is "\"\"" which generates the following error:

Yeah originally I had "" and I've also tried "\"\"", "''" and various quantities of backslash characters. It's ok I'm using a work-around (use the standard .summary("foo") condition that generates a "contains" query, then loop through the results and try to find the exact match). Obviously not an efficient solution so would be good to find out how to make this work

Hi Nathon,

did you try to add "\"\"" instead of "" ?

Long[]).and().not().issue(issue.getKey()).and().field("issueFunction").inFunc("issueFieldExactMatch", "\"\"", "summary", currentSummary).buildQuery()

Try passing com.atlassian.query.operand.EmptyOperand.OPERAND_NAME instead empty string.
