jjs にグローバルな関数を追加します。

init-naz-test.js

load('init-naz.js');
cp('http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.3.0/ivy-2.3.0.jar', 'ivy-2.3.0.jar');
unzip('http://archive.apache.org/dist/ant/ivy/2.3.0/apache-ivy-2.3.0-bin.zip', '.');

動かし方はこんな感じ：

jjs -Djava.net.useSystemProxies=true init-naz-test.js

jrunscript -Djava.net.useSystemProxies=true init-naz-test.js

load() は jjs と jrunscript で共通なので、この内容ならどちらでも動く。

jrunscript ならスクリプトを引数で渡せるからファイルは１つ減らせるか...

@echo off
jrunscript -e ^
load('init-naz.js');^
cp('http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.3.0/ivy-2.3.0.jar','ivy-2.3.0.jar');^
unzip('http://archive.apache.org/dist/ant/ivy/2.3.0/apache-ivy-2.3.0-bin.zip','.');
