我有一个我正在尝试编译的 groovy 脚本，以便它可以在没有 groovy 的系统上运行。我用这篇文章作为参考。它似乎可以编译，但是当我运行脚本时，它会启动，然后给我一个 java.lang.ClassNotFoundException。
package org.something.groovy.project
import groovy.xml.MarkupBuilder
import groovy.xml.StreamingMarkupBuilder
class LibraryParser
{
public static void main(args)
{
println "setting file path"
def xmlFile = "collection.nml"
println "parsing collection"
def xml = new XmlParser().parse(xmlFile)
println "beginning loop"
def counter = 0
xml.COLLECTION.ENTRY.each{
if (it.MUSICAL_KEY[0] != null)
{
switch (it.MUSICAL_KEY[0].@VALUE)
{
case "0":
it.INFO.@KEY = "8B"
break
case "1":
it.INFO.@KEY = "3B"
break
case "2":
it.INFO.@KEY = "10B"
break
case "3":
it.INFO.@KEY = "5B"
break
case "4":
it.INFO.@KEY ="12B"
break

it.INFO.@KEY ="7B"

default:
println "something went wrong!"
println it.MUSICAL_KEY[0].@VALUE
break
}
}
}
new File("C:/workspacGROOVY/org.something.groovy/collection_out.nml").withWriter('UTF-8') { out ->
out << new StreamingMarkupBuilder().bind { mkp.pi( xml:[ version:'1.0', encoding: 'UTF-8', standalone:'no' ] ) }
new XmlNodePrinter(new PrintWriter(out)).print(xml)
}
println "Finished"
}
}

这是我正在使用的 GroovyWrapper

这是我用来编译它的命令：
C:\workspacGROOVY\org.something.groovy\src>groovy org\something\groovy\project\G
roovyWrapper -c -m org/something/groovy/project/LibraryParser
[echo] Compiling org\something\groovy\project\LibraryParser.groovy
[jar] Building jar: C:\workspacGROOVY\org.something.groovy\src\org\somethi
ng\groovy\project\LibraryParser.jar
[echo] Run script using: 'java -jar org/something/groovy/project/LibraryPar
ser.jar ...'
我是否遗漏了一些应该添加缺失类的内容？Wrapper 在编译时还创建了另外两个类。
