问题描述

我有一个build.xml文件，该文件使用xjc生成一些Java类.在Java 1.8中一切正常，但是更新到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文件中达到此点时发生错误:

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>

我尝试利用JDK目录中的xjc.exe，但是比较基准线和Java 9版本会发现文件丢失或不完整.如果有帮助，这是我所做的:

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，以便xjc仍然可以工作?欢迎任何建议.

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基础在这里.

检查JAXB2基础版本，其中有Ant示例项目(例如购买订单示例).

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

这是相关部分:

<target name="generate-sources">
    <taskdef name="xjc" classname="org.jvnet.jaxb2_commons.xjc.XJC2Task">
        <!-- XJC2 Task classpath -->
        <classpath>
            <fileset dir="${basedir}/lib">
                <include name="activation-*.jar"/>
                <include name="jaxb-api-*.jar"/>
                <include name="jaxb-impl-*.jar"/>
                <include name="jaxb-runtime-*.jar"/>
                <include name="jaxb-core-*.jar"/>
                <include name="jsr173_api-*.jar"/>
                <include name="stax-api-*.jar"/>

                <include name="jaxb-xjc-*.jar"/>
                <include name="jaxb2-basics-ant-*.jar"/>

                <include name="slf4j-*.jar"/>
                <include name="jcl-over-slf4j-*.jar"/>
            </fileset>
        </classpath>
    </taskdef>
    <mkdir dir="${basedir}/target/generated-sources/xjc"/>
    <xjc destdir="${basedir}/target/generated-sources/xjc" extension="true">
        <!--arg line="
            -Xequals
            -XhashCode
            -XtoString
            -Xcopyable
            -Xmergeable
            -Xinheritance"/-->
        <binding dir="${basedir}/src/main/resources">
            <include name="**/*.xjb"/>
        </binding>
        <schema dir="${basedir}/src/main/resources">
            <include name="**/*.xsd"/>
        </schema>
        <!-- Plugins -->
        <classpath>
            <fileset dir="${basedir}/lib">
                <!-- JAXB2 Basics library -->
                <!--include name="jaxb2-basics-plugins-*.jar"/-->
            </fileset>
        </classpath>
    </xjc>
</target>
