gmaven-plugin errore del parser SAX

Question

Oggi, ho incontrato uno strano problema con il codice Groovy che viene eseguito da Maven (usando gmaven-plugin). Sto usando Groovy solo in unit test. Tutti i test di unità passano in Eclipse, tuttavia, ottengo errori su alcuni test di unità quando sono in esecuzione con Maven.

Il codice Groovy problematica comporta la manipolazione XML. E 'un metodo di categoria che aggiunge un attributo a payload 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)
    }
 }

sto ottenendo il seguente errore:

  <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.

E GMaven plug aspetto di configurazione in questo modo:

<plugin>
    <groupId>org.codehaus.gmaven</groupId>
    <artifactId>gmaven-plugin</artifactId>
    <version>1.3</version>
    <extensions>true</extensions>
    <executions>
        <execution>
            <goals>
                <goal>testCompile</goal>
            </goals>
            <configuration>
                <sources>
                    <fileset>
                        <directory>${pom.basedir}/src/test/groovy</directory>
                        <includes>
                            <include>**/*.groovy</include>
                        </includes>
                    </fileset>
                </sources>
            </configuration>
        </execution>
    </executions>
</plugin>

Si prega di aiuto. Ho provato di tutto. Perché funziona in Eclipse? In realtà sono sicuro che il problema non è a causa del metodo di categoria.

Answer 1

Non ho potuto trovare ciò che stava causando che il comportamento errato, tuttavia, sono riuscito a trovare una soluzione che usi XmlParser invece di XmlSlurper e non usa XmlUtil.serialize() per preparare risultato 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()
    }
 }

Questo funziona in Eclipse e da Maven della riga di comando.

Answer 2

mi rendo conto che non è un reale risposta, ma ho lottato con me stesso GMaven per diversi mesi. Poi sono passato a Gradle e improvvisamente le nubi si aprirono. Grande per la costruzione di progetti Java e usando Groovy per testare ecc GMaven sembrava sul punto morto per me all'inizio di quest'anno. Se ti ostini a usare GMaven, credo di aver ottenuto il massimo da esempi di utilizzo di Spock con Maven in quanto la documentazione GMaven sembrava fuori data per me.

In bocca al lupo!
