How to encode Java files in UTF-8 using Apache Ant?
提问by Madeline
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?
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？
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:
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。否则我会收到一个错误：
warning: unmappable character for encoding utf-8
警告：用于编码 utf-8 的不可映射字符
Here is my code:
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" />

<classpath>
<path refid="cxf.classpath"/>
</classpath>
</java>
</else>
</if>
</sequential>
</macrodef>
What should I do here to make

在utf-8 中编码java 文件？
回答by Christopher Peisert
Ant's <copy>task has attributes encodingand outputencoding.
Ant 的<copy>任务具有属性encoding和outputencoding.
Single Java File
单个 Java 文件
<copy file="myJavaFile.java" tofile="myJavaFile.java" overwrite="true"
encoding="ISO-8859-1" outputencoding="UTF-8" />
All Java Files in a Directory
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>
Simply change ISO-8859-1to the encoding format of your Java files.
只需更改ISO-8859-1为 Java 文件的编码格式即可。
