如何使用 Apache Ant 以 UTF-8 编码 Java 文件? [英] How to encode Java files in UTF-8 using Apache Ant?

问题描述

在我的 build.xml 文件中，我通过 cxf 获取了一些 Java 文件.其中一些 Java 文件需要以 UTF-8 编码.如何使用 Ant 将编码更改为 UTF-8?

In my build.xml file I fetch some Java files by cxf. Some of these Java files need to be encoded in UTF-8. How can I use Ant to change the encoding to UTF-8?

PS:我找到了有关如何将 javac 的编码设置为 UTF-8 的说明，但在 javac 之前，我需要 Java 文件为 UTF-8.否则我会得到一个错误:

PS: I found instructions for how to set the encoding for javac to UTF-8, but prior to javac I need Java files to be in UTF-8. Otherwise I get an error:

警告:编码 utf-8 的字符不可映射

warning: unmappable character for encoding utf-8

这是我的代码:

<macrodef name="lpwservice">
    <attribute name="name"/>
    <attribute name="package"/>
    <sequential>
        <property name="wsdlfile" value="${portal.basedir}/lpw/wsdl/@{name}.wsdl"/>

        <mkdir dir="${portal.basedir}/lpw/wsdl"/>
        <get src="${lpw.baseuri.cxf}/@{name}?wsdl" dest="${portal.basedir}/lpw/wsdl/@{name}.wsdl.new"/>
        <if>
            <and>
                <filesmatch file1="${portal.basedir}/lpw/wsdl/@{name}.wsdl" file2="${portal.basedir}/lpw/wsdl/@{name}.wsdl.new"/>
                <uptodate targetfile="${portal.basedir}/lpw-wsdl.jar" srcfile="${portal.basedir}/lpw/wsdl/@{name}.wsdl"/>
            </and>
            <then>
                <echo message="${wsdlfile} is up to date" level="info"/>
                <delete file="${portal.basedir}/lpw/wsdl/@{name}.wsdl.new"/>
            </then>
            <else>
                <echo message="${portal.basedir}/lpw/wsdl/@{name}.wsdl needs update" level="info"/>
                <move file="${portal.basedir}/lpw/wsdl/@{name}.wsdl.new" tofile="${portal.basedir}/lpw/wsdl/@{name}.wsdl" overwrite="true" />
                <java classname="org.apache.cxf.tools.wsdlto.WSDLToJava" fork="true" failonerror="true">
                    <arg value="-client"/>
                    <arg value="-d"/>
                    <arg value="${portal.basedir}/lpw/src"/>
                    <arg value="${portal.basedir}/lpw/wsdl/@{name}.wsdl"/>
                    <classpath>
                        <path refid="cxf.classpath"/>
                    </classpath>
                </java>
            </else>
        </if>
    </sequential>
</macrodef>

我应该在这里做什么

<java classname="org.apache.cxf.tools.wsdlto.WSDLToJava" fork="true" failonerror="true">

用utf-8编码java文件?

to encode java files in utf-8?

推荐答案

Ant 的 任务具有encoding 和outputencoding 属性.

Ant's <copy> task has attributes encoding and outputencoding.

<copy file="myJavaFile.java" tofile="myJavaFile.java" overwrite="true"
    encoding="ISO-8859-1" outputencoding="UTF-8" />

目录中的所有 Java 文件

<property name="source.dir" location="/path/to/java/files" />

<copy todir="${source.dir}" overwrite="true"
    encoding="ISO-8859-1" outputencoding="UTF-8">
  <fileset dir="${source.dir}" includes="*.java" />
</copy>

只需将 ISO-8859-1 更改为您的 Java 文件的编码格式.

Simply change ISO-8859-1 to the encoding format of your Java files.
