从Java中使用groovy.util.AntBuilder [英] Using groovy.util.AntBuilder from java
本文介绍了从Java中使用groovy.util.AntBuilder的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在常规的groovy.util.AntBuilder可用于如。解压缩文件到文件夹:
In groovy the groovy.util.AntBuilder can be used to eg. unzip a file into a folder:
AntBuilder ant = new AntBuilder();
ant.unzip(src: file.getPath(), dest: outputFolder.getPath());
现在我想这样做相同的,但在Java。它不可能直接调用解压。我认为,多数民众赞成在invokeMethod中是什么:
Now I would like to do the same but from java. Its not possible to call unzip directly. I assume thats what the invokeMethod is for:
AntBuilder ant = new AntBuilder();
String[] args = new String[4];
args[0] = "src";
args[1] = file.getPath();
args[2] = "dest";
args[3] = outputFolder.getPath();
ant.invokeMethod("unzip", args);
上面给出了:
No signature of method: groovy.util.AntBuilder.unzip() is applicable for argument types: (java.lang.String, java.lang.String, java.lang.String, java.lang.String) values:
任何想法?
我曾尝试谷歌文档/示例使用从Java的AntBuilder,但我只找到它的地方,从常规使用的例子。
I have tried to google docs/examples for using the AntBuilder from java, but I have only found examples where its used from groovy.
推荐答案
右键,得到了一台电脑,并给它一去:
Right, got to a computer and gave it a go:
由于这个Java类:
import groovy.util.AntBuilder ;
import java.io.File ;
import java.util.HashMap ;
public class Test {
public static void main( String[] args ) throws Exception {
if( args.length != 2 ) {
System.err.println( "Need 2 args. Input zip file and output folder" ) ;
System.exit( 1 ) ;
}
final File file = new File( args[ 0 ] ) ;
final File outputFolder = new File( args[ 1 ] ) ;
AntBuilder ant = new AntBuilder() ;
ant.invokeMethod( "unzip", new HashMap() {{
put( "src", file.getPath() ) ;
put( "dest", outputFolder.getPath() ) ;
}} ) ;
}
}
您可以再用编译:
javac -cp $GROOVY_HOME/embeddable/groovy-all-2.0.5.jar Test.java
然后运行:
java -cp $GROOVY_HOME/lib/*:. Test /path/to/zip /destination/folder
和它应该工作
