问题描述

我有一个 build.xml 文件，它使用 xjc 生成一些 Java 类.在 Java 1.8 中一切正常，但更新到 Java 9 会导致以下错误:

I have a build.xml file that uses xjc to generate some Java classes. Everything builds fine in Java 1.8, but updating to Java 9 causes the following error:

xjc-gen-boxes:
  [xjc] C:\Users\dev\Documents\Dev\bc\bcce2\build\gensrc\co\boxes\v2 is not found and thus excluded from the dependency check
  [xjc] Compiling file:/C:/Users/dev/Documents/Dev/bc/bcce2/co/src/co/kat/install/boxes/Box.xsd

在 build.xml 文件中到达此点时发生错误:

The error occurs when reaching this point in the build.xml file:

<taskdef name="xjc" classname="com.sun.tools.xjc.XJC2Task">
    <classpath>
        <pathelement path="${basedir}/lib/webservices-tools.jar"/>
        <pathelement path="${basedir}/lib/webservices-rt.jar"/>
        <pathelement path="${basedir}/lib/jaxb-commons-lang-plugin-2.2.jar" />
        <pathelement path="${basedir}/lib/commons-lang-2.4.jar" />
    </classpath>
  </taskdef>

<target name="xjc-gen-boxes">
    <xjc destdir="${path.out.gensrc}">
          <arg value="-Xcommons-lang"/>
          <schema dir="${boxes.schema.home.translated}" includes="*.xsd"/>
          <produces dir="${path.out.gensrc}/co/boxes/v2"/>
    </xjc>
</target>

我已经尝试使用在 JDK 目录中找到的 xjc.exe，但是基线和 Java 9 构建之间的比较显示文件丢失或不完整.如果有帮助，这就是我所做的:

I've tried utilizing the xjc.exe found in the JDK directory, but a comparison between the baseline and Java 9 build revealed files missing or incomplete. Here's what I did with that, if it helps:

<target name="xjc-gen-boxes">   
    <mkdir dir="${path.out.gensrc}/co/boxes/v2"/> 
    <exec executable="${env.JAVA_HOME}/bin/xjc.exe">
        <arg value="${boxes.schema.home.translated}/*.xsd"/>
        <arg value="-d"/>
        <arg value="${path.out.gensrc}"/>
        <arg value="-classpath"/>
        <arg value="${basedir}/lib/commons-lang-2.4.jar"/>
        <arg value="${basedir}/lib/jaxb-commons-lang-plugin-2.2.jar"/>
        <arg value="${basedir}/lib/webservices-rt.jar"/>
        <arg value="${basedir}/lib/webservices-tools.jar"/>
    </exec>
</target>

有没有办法修改 build.xml 文件，让 xjc 仍然可以工作?欢迎提出任何建议.

Is there a way to modify the build.xml file so that xjc can still work? Any suggestions are welcome.

推荐答案

JAXB2 Basics 在这里.

查看 JAXB2 Basics releases，有 Ant 示例项目(例如 采购订单样本).

Check JAXB2 Basics releases, there are Ant sample projects (for instance the Purchase Order sample).

以下是相关部分:

<target name="generate-sources">
    <taskdef name="xjc" classname="org.jvnet.jaxb2_commons.xjc.XJC2Task">
