gmaven-plugin SAX解析器錯誤

Question

今天，我遇到了一個從Maven運行的Groovy代碼的奇怪問題（使用gmaven-plugin）。我只在單元測試中使用Groovy。所有的單元測試都在Eclipse中傳遞，但是，當我使用Maven運行它時，某些單元測試出現錯誤。

有問題的Groovy代碼涉及到XML操作。這是一種向XML有效負載添加屬性的類別方法。

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) 
    } 
} 

，我發現了以下錯誤：

<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.

而且GMaven插件的配置是這樣的：

<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> 

請幫助。我嘗試了一切。爲什麼它在Eclipse中工作？我確定問題不在於類別方法。

Answer 1

我找不到什麼造成該故障的行爲，但是，我已經成功地發現，使用XmlParser，而不是XmlSlurper，並且不使用XmlUtil.serialize()準備XML結果的解決方法：

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() 
    } 
} 

這在Eclipse和Maven命令行中工作。

Answer 2

我意識到這不是一個真的答案，但我與GMaven自己奮鬥了好幾個月。然後，我轉向了gradle，突然雲層分開了。非常適合構建Java項目和使用Groovy進行測試等。今年早些時候，GMaven對我來說似乎已經死了。如果你堅持使用GMaven，那麼我認爲自從GMaven的文檔對我來說似乎已經過時了以後，我可以充分利用Spock和Maven的例子。

祝你好運！
