Exception Writing Output From API

[mandrachek]

I'm utilizing the CFLintAPI, and am attempting to call result.writeHTML("default.xsl",writer) - it doesn't matter which htmlStyle value I provide, I get:

net.sf.saxon.trans.XPathException: Values of 'standalone' and 'omit-xml-declaration' conflict

Looks like that method is used two places
https://github.com/cflint/CFLint/search?q=writeHTML&unscoped_q=writeHTML
you tried "plain.xsl" as well?

[mandrachek]

Yeah, I tried all of the ones in https://github.com/cflint/CFLint/tree/master/src/main/resources/findbugs
I know had a similar issue previously when working with spotbugs (which is the replacement for findbugs) - I think it might be down to changes in the XML parsing between Java 7 and Java 8.

spotbugs/spotbugs-gradle-plugin#114

I get this error if I use plain.xsl or default.xsl and writeHTML or writeFindBugsXml

Error evaluating ((attr{sequence=...}, ...)) on line 13 column 42

This is the stack trace from writeHTML():

FWIW, I'm running this from a gradle task using Gradle 6.7:

buildscript {
    repositories {
         jcenter()
         mavenCentral()
    }
    dependencies {
                classpath 'com.github.cflint:CFLint:1.5.0'
    }
}

import com.cflint.api.CFLintAPI
import com.cflint.api.CFLintResult
import com.cflint.Levels

task cflint(group: 'verification') {

    doFirst {
        mkdir "${project.buildDir}/reports/cflint"
    }

    doLast {
        CFLintAPI api = new CFLintAPI()

        def scanFiles = new ArrayList<String>()

        fileTree("src").each {
            if (it.name.toLowerCase().endsWithAny("cfc","cfm")) {
                scanFiles.add(it.absolutePath)
            }
        }
        CFLintResult result = api.scan(scanFiles)

        result.writeXml(
                file("${project.buildDir}/reports/cflint/main.xml").newWriter()
        )

        /*
            --- these both fail ---
        result.writeHTML(
            "plain.xsl",
            file("${project.buildDir}/reports/cflint/main.html").newWriter()
        )

        result.writeFindBugsXml(file("${project.buildDir}/reports/cflint/main.xml").newWriter())
         */
    }
