[jira] [Commented] (MJAR-142) 'Negative time' when trying to create
an empty jar
[ https://issues.apache.org/jira/browse/MJAR-142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15155708#comment-15155708 ]
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;
}
}

> 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:
