项目的构建过程正在受到影响,除非它变为自动化。
我从最近开始使用ANTLR。 ANT似乎是为此目的而建立的工具。编译,jar和测试...但是为此目的我找到了脚本build.xml的小代码源。
那么你们想为你的antlr项目分享你的模板build.xml(Java任务或ANTLR任务会没问题)吗?谢谢。

这大致是我使用的:
<?xml version="1.0" encoding="UTF-8"?>
<project name="YourProject">
<property name="main.package" value="yourproject"/>
<property name="parser.package" value="${main.package}/parser"/>
<property name="main.src.dir" value="src/main"/>
<property name="test.src.dir" value="src/test"/>
<property name="grammar.src.dir" value="src/grammar"/>
<property name="grammar.file" value="${grammar.src.dir}/YourGrammar.g"/>
<property name="build.dir" value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="main.build.dir" value="${classes.dir}/main"/>
<property name="test.build.dir" value="${classes.dir}/test"/>
<path id="classpath">
<pathelement location="${main.src.dir}"/>
<pathelement location="${test.src.dir}"/>
<pathelement location="${main.build.dir}"/>
<pathelement location="${test.build.dir}"/>
<!-- the ANTLR jar is in the lib directory, of course -->
<fileset dir="lib">
<include name="*.jar"/>
</fileset>
</path>
<!-- init target -->

</javac>
<javac srcdir="${test.src.dir}" destdir="${test.build.dir}" includeantruntime="false">

</javac>
</target>
<target name="generate" depends="init" description="Generates the lexer and parser from the .g grammar file.">

<classpath refid="classpath"/>
</java>
<!--

-->
<antcall target="compile"/>
</target>
<!-- other targets -->
</project>

这是我的核心部分,我认为整合得更好一些。我不确定何时添加了ANTLR的-make
选项 - 我使用3.2。
clean
编辑<project name="MyProject">
<property name="lib.antlr" value="lib/antlr-3.2.jar" />
<property name="src.dir" value="${user.dir}" />
<property name="src.java" value="${src.dir}/java" />
<property name="build.dir" value="build" />
<property name="build.src" value="${build.dir}/src" />
<property name="build.classes" value="${build.dir}/classes" />
<path id="compile.class.path">
<pathelement location="${build.classes}" />
<fileset dir="lib">
<include name="**/*.jar" />
</fileset>
</path>
<target name="clean">
<delete dir="${build.dir}" />
<delete dir="${reports.dir}" />
</target>
<target name="generate" description="Generate parsers from ANTLR grammars">
