问题 How do I disable a package filter? I keep getting this message.... Ignoring unknown package filter 'build-tools-23.0.0_rc2' Warning: The package filter removed all packages.

问题 This question already has answers here : Why are modifiers allowed for a package when they don't seem to do anything? (2 answers) Closed 6 years ago .

问题 After following http://ubuntuforums.org/showthread.php?t=406069 I got to know how to make a .deb file which automatically places the Python file as an executable to /usr/bin directory. I want my program to have a structure like that of "grep". Which libraries should I use, and what should be the structure of the programs. At libraries, do I have to use Get::Opt library? By the "grep structure" I mean the following: program-name func-name -a arg1 --b arg2 should work man program-name should

问题 I'm running a business where we are creating email stationeries for people. We have some Mac users that currently have to download a zip file and manually copy that to their mail stationeries directory. I want to automate that process and allow Mac users to download directly a package that will copy those files automatically.

问题 I was writing some practice programs for my java certification this morning, and noticed that I had mistyped a package name, so it didn't match the subdirectory the java file was in. I compiled the code expecting an error, but everything compiled file -- not even a warning. I googled around a bit, and most of the pages I read said that the package name had to match the subdirectory. My experience shows that's not the case. When I attempted to run the program, it didn't work because the .class

问题 I am working on a WPF open source markdown editor and I am at the point where I need to save and load documents. A "document" contains 3 files: A XML file for metadata A MD file for the markdown text A HTML file for the HTML view of the document. At this point for testing I create a directory for each document to hold these files, however this is not very convenient. I need all those files to be packaged inside a single file so users wouldn't be confused with 3 separate files. I did a bit of

问题 On various web examples I see imports such as: import org.apache.commons.net.ftp.FTPClient; I don't understand how to use these, and the apache website is fairly unclear. How to I use these classes? I'm expecting I need to download something, but a little direction would be greatly appreciated. 回答1: You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath. For Commons Net you need to download the binary files from Commons
