Ant

From Chaehyun

• Cause: Could not load a dependent class com/jcraft/jsch/LoggerIt is not enough to have Ant's optional JARs 메시지가 나올 경우
  • http://www.jcraft.com/jsch/ 에서 jsch-0.1.45.jar 파일을 다운 받고
  • D:\eclipse\plugins\org.apache.ant_1.8.2.v20110505-1300\lib 에 복사
  • eclipse에서 windows - preference - ant - runtime - ant home에 추가
• scp 관련

• sample xml

<?xml version="1.0"?>
<project name="XlosAnt" default="jar" basedir="." >
 <property name="src.dir" value="${basedir}/src" />
 <property name="classes.dir" value="${basedir}/bin" />
 <property name="jar.dir" value="${basedir}/dist" />
 <property name="jar.name" value="xlos.jar" />

<target name="dist" depends="jar">
    <scp file="${jar.dir}/${jar.name}"  trust="true" todir="hdfs:****@host:/home/hdfs/users/chaehyun" />
</target>

 <target name="compile" >
  <javac srcdir="${src.dir}" destdir="${classes.dir}" />
 </target>

 <target name="jar" depends="compile">
  <jar jarfile="${jar.dir}/${jar.name}" 
       basedir="${classes.dir}" 
       includes="**/*.class" />

 <target name="clean" >
  <delete dir="${classes.dir}/classes/*" />

• 특정 디렉토리로 옮기기

<target name="deploy-local" depends="jar">
<move file="${build.dir}/${final.name}.jar" tofile="runtime/local/lib/${final.name}.jar"/>
</target>

• library jar 포함하기

  • http://ant.apache.org/manual/Tasks/javac.html

	<path id="dyna.jars">
 	    <fileset dir="${basedir}/lib">
	        <include name="**/*.jar"/>
	    </fileset>	   
	    <fileset dir="${basedir}/lib2">
	        <include name="**/*.jar"/>
	    </fileset>	 
	</path>
<target name="compile" >
  <javac srcdir="${src.dir}"
  	destdir="${classes.dir}"
  	classpathref="dyna.jars"
  />

• 외부 jar 포함해서 통으로 만들기 (jar merge)

<zip destfile="out.jar">
    <zipgroupfileset dir="lib" includes="*.jar"/>
</zip>
