今日、私はMavenから実行されるGroovyコードで奇妙な問題に遭遇しました（を使用してgmaven-plugin）。Groovyはユニットテストでのみ使用しています。すべての単体テストはEclipseで合格しますが、Mavenで実行すると、特定の単体テストでエラーが発生します。

問題のあるGroovyコードには、XML操作が含まれます。これは、XMLペイロードに属性を追加するカテゴリメソッドです。

 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)
    }
 }

次のエラーが発生します。

  <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.

また、GMavenプラグインの構成は次のようになります。

助けてください。私はすべてを試しました。なぜEclipseで動作するのですか？私は実際、問題はカテゴリー方式によるものではないと確信しています。

その誤った動作の原因を見つけることができませんでしたが、XML結果の準備に使用するXmlParser代わりに使用する回避策を見つけることができました。XmlSlurperXmlUtil.serialize()

 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()
    }
 }

これはEclipseおよびMavenコマンドラインから機能します。

これは本当の答えではないことはわかっていますが、私は数か月間GMavenと苦労しました。それから私はgradleに切り替えました、そして突然雲は別れました。Javaプロジェクトを構築したり、Groovyをテストなどに使用したりするのに最適です。GMavenは今年の初めに私には死んでいるように見えました。GMavenの使用を主張する場合、GMavenのドキュメントが古くなっているように見えたので、MavenでSpockを使用した例を最大限に活用したと思います。

幸運を！
