我有我想要編譯，以便它可以不用常規的系統上運行Groovy腳本。我正在使用this文章作爲參考。它似乎編譯好，但是當我運行腳本，它啓動，然後給我一個java.lang.ClassNotFoundException。Groovy：在拋出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][email protected])
{
case "0":
[email protected] = "8B"
break
case "1":
[email protected] = "3B"
break
case "2":
[email protected] = "10B"
break
case "3":
[email protected] = "5B"

}
}
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"
}
}
在命令提示符下的錯誤：
setting file path //normal output of the script
parsing collection
beginning loop

的GroovyWrapper這是我使用編譯命令：
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 ...'
我失去了somethi沿着這些線應該添加缺失的類嗎？ Wrapper在編譯時還創建了另外兩個類。
腳本是什麼？任何舊腳本是否失敗？或者只是這個特定的未顯示的腳本？ –
@tim_yates由於這是我的第一個Groovy程序，因此我沒有其他腳本來測試它。我會繼續寫下來，真的很快。我還在腳本中添加了腳本。 –
@tim_yates一個簡單的「HelloWorld」的劇本工作正常 –
