【问题描述】：

最近，在执行 Maven 发布插件的 release:prepare 目标时，我们的 Ci 工作让我眼前一亮。我收到一个奇怪的 SAX 解析错误：Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 6; The processing instruction target matching "[xX][mM][lL]" is not allowed. build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:400) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:327) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1472) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLScanner.scanPIData(XMLScanner.java:746) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanPIData(XMLDocumentFragmentScannerImpl.java:1014) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLScanner.scanPI(XMLScanner.java:714) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver.next(XMLDocumentScannerImpl.java:907) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:602) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:112) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:505) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:842) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:771) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:141) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1213) build 25-Sep-2019 13:42:25 at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:643) build 25-Sep-2019 13:42:25 at org.jdom.input.SAXBuilder.build(SAXBuilder.java:453)

虽然我可以mvn clean install这个项目就好了...

【参考方案1】：

好的，原来其中一个子模块在 pom.xml 的开头有一个换行符。 Maven 本身显然并不关心这个，但是 Maven 发布插件无法解析这个并炸毁了我。
