Error de analizador de saxo gmaven-plugin

Question

Hoy, he encontrado un problema extraño con el código groovy que se ejecuta desde Maven (usando gmaven-plugin). Estoy usando Groovy solo en pruebas unitarias. Todas las pruebas unitarias pasan en Eclipse, sin embargo, obtengo errores en ciertas pruebas unitarias cuando las ejecuto con Maven.

El código maravilloso problemático implica la manipulación XML. Es un método de categoría que agrega un atributo a la carga útil XML.

 class BaseTestCategoryMethods {
  private static XmlSlurper slurper = new XmlSlurper(false, false)
    public static String schemaVersion(String self, String version) {
    def root = slurper.parseText(self)
    root.@version = version
    return XmlUtil.serialize(root)
    }
 }

Recibo el siguiente error:

  <error message="org.xml.sax.SAXParseException: Premature end of file." type="net.sf.saxon.trans.XPathException">net.sf.saxon.trans.XPathException: org.xml.sax.SAXParseException: Premature end of file.

Por favor ayuda. Intenté todo. ¿Por qué funciona en Eclipse? De hecho, estoy seguro de que el problema no se debe al método de categoría.

Answer 1

No pude encontrar lo que estaba causando ese comportamiento defectuoso, sin embargo, he logrado encontrar una solución que use XmlParser en vez de XmlSlurper y no usa XmlUtil.serialize() Para preparar el resultado XML:

 class BaseTestCategoryMethods {
    public static String schemaVersion(String self, String version) {
        def root = new XmlParser().parseText(self)
        root.attributes().put("version", version)
        StringWriter sw = new StringWriter()
        def printer = new XmlNodePrinter(new PrintWriter(sw), "")
        printer.setPreserveWhitespace(true)
        printer.print(root);
        return sw.toString().readLines().join()
    }
 }

Esto funciona en Eclipse y desde la línea de comandos Maven.

Answer 2

Me doy cuenta de que esto no es un real Respuesta, pero luché con Gmaven durante varios meses. Luego cambié a Gradle y de repente las nubes se separaron. Ideal para construir proyectos Java y usar Groovy para pruebas, etc. Gmaven me pareció muerto a principios de este año. Si insiste en usar Gmaven, creo que obtuve el máximo provecho de usar Spock con Maven ya que la documentación de Gmaven me pareció desactualizado.

¡Buena suerte!
