Rakhunathan commented on MJAR-142:
----------------------------------
Not really sure why the problem occurs, but found out the solution. The error
occurs because, one or more file that you are trying to build, has a negative
time.(file.getLastModified() returns a negative value). If its a huge project,
might be hard to track which of them has gone wrong. Below code might help
package com.example;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class ModifyAll {
public static void main(String[] args) throws IOException {
List<File> folderList = new ArrayList<>();
List<File> fileList = new ArrayList<>();
File folder = new File("D:/Rakhu/Copy/projectfolder/src");
FileVO baseFileVO = segregateFiles(folder);
fileList.addAll(baseFileVO.getFileList());
folderList.addAll(baseFileVO.getFolderList());
for (int i = 0; i < folderList.size(); i++) {
FileVO thisVO = segregateFiles(folderList.get(i));
fileList.addAll(thisVO.getFileList());
folderList.addAll(thisVO.getFolderList());
}
for (int i = 0; i < fileList.size(); i++) {
Date dte = new Date();
long milliSeconds = dte.getTime();
System.out.println("Setting Time For " + fileList.get(i) + " as " +
milliSeconds);
fileList.get(i).setLastModified(milliSeconds);
}
System.out.println("Succesfully Modified..!!!");
}
public static FileVO segregateFiles(File folder) {
List<File> folderList = new ArrayList<>();
List<File> fileList = new ArrayList<>();
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
fileList.add(listOfFiles[i]);
} else {
folderList.add(listOfFiles[i]);
}
System.out.println(listOfFiles[i]);
}
return new FileVO(fileList, folderList);
}
}
FileVO.java
package com.example;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
public class FileVO {
List<File> fileList = new ArrayList<>();
List<File> folderList = new ArrayList<>();
public FileVO(List<File> fileList, List<File> folderList) {
this.fileList = fileList;
this.folderList = folderList;
}
public List<File> getFileList() {
return fileList;
}
public void setFileList(List<File> fileList) {
this.fileList = fileList;
}
public List<File> getFolderList() {
return folderList;
}
public void setFolderList(List<File> folderList) {
this.folderList = folderList;
}
}

> Key: MJAR-142
> URL: https://issues.apache.org/jira/browse/MJAR-142
> Project: Maven JAR Plugin
> Issue Type: Bug
> Affects Versions: 2.3
> Environment: Windows 7
> maven 3.0.2
> Reporter: bblasi bblasi
> Assignee: Karl Heinz Marbaise
>
> When I try to run 'package' on a multi-module project one of the modules
> fails. The only difference on this module being it will run an ant script so
> no jar, or an empty one up until now, would be generated.
> Plugin 2.2 will do the job. Plugin 2.3 fails on '-X package' with:
