问题 Edit 20140716 : Solution found tl;dr = exec-maven-plugin does not recognise .cmd files, but only .bat files, as executable scripts. Rename grunt.cmd --> grunt.bat , bower.cmd --> bower.bat , etc. as a workaround. Having done npm install -g grunt-cli on my system, grunt is most certainly on the PATH When I run maven install however, this doesn't seem to register. [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (build-spa-bower) on project foobar: Command execution

问题 How do I set custom search paths for the terminfo database when building ncurses from source? To be more specific, how do I force the primary directory to be searched in '~/.terminfo'? 回答1: From the terminfo manpage: Fetching Compiled Descriptions If the environment variable TERMINFO is set, it is interpreted as the pathname of a directory containing the compiled description you are working on. Only that directory is searched. If TERMINFO is not set, the ncurses version of the terminfo reader

问题 I use Windows Subsystem Linux(Ubuntu 18.04) in my Win10, and I install a Maven in it. Besides, I install a maven in Win10 before. Now when I used mvn compile in WSL, it told me that maven compile fail. I use which mvn and find that it references to the Maven installed in Win10. Besides, I run env and find that Win10's Path is added to the WSL's Path. I don't want to use any thing in Win10's Path when I use WSL, how should I do? 回答1: For Windows build LOWER than 17713: WSL uses WSL

问题 I need to construct a file path inside a Perl script. Which path separator should I use to allow my script to work on both Windows and Unix? Keep in mind that Windows needs a drive letter. 回答1: You want File::Spec's catpath : catpath() Takes volume, directory and file portions and returns an entire path. Under Unix, $volume is ignored, and directory and file are concatenated. A '/' is inserted if need be. On other OSes, $volume is significant. $full_path = File::Spec->catpath( $volume,

问题 I am using <p:fileUpload> component. Is it possible to preselect and show the selected file in field before the browse button? I am using Mojarra 2.0.3, PrimeFaces 2.2 RC2, GlassFish 3. 回答1: No, if this was possible, this would have been a huge security hole. You would then in theory be able to let the selected file point to C:/path/to/passwords.txt and then use JavaScript to submit the form and so silently get a file with sensitive data from the client without its permission.

问题 I've set a script in my root crontab that is supposed to restart my machine with the reboot command. However, I am getting a reboot: command not found despite the fact that reboot is in the root user's path. $ sudo su $ which reboot /sbin/reboot $ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin My script: #!/bin/bash ping 8.8.8.8 -c 1 > /dev/null 2>&1; exit_code=$? time_stamp=$(date +"%Y%m%d-%H%M") if [ $exit_code -ne 0 ]; then (1>&2 echo "$time_stamp

问题 I am getting a error message like this: The library libraryname .dll could not be loaded by Windows. Make sure that the library is in you Path environment variable. Exception in thread "main" java.lang.UnsatifiedLinkError: no libraryname in java.library.path. This error is from me trying to run a jar file on Windows XP via cmd. I am wondering, where exactly is java.library.path? I've already added C:\Program Files\Java\jdk1.6.0_26 to my PATH but it still gives me the error. How would you go

问题 I generally use IPython and only recently noticed that the the search path for imports is wrong in the regular python shell. From what I understand, sys.path inherits from PYTHONPATH (although I don't know where PYTHONPATH lives), is this different in IPython? I'm worried that this effecting installations. For instance I just tried pip install --upgrade gensim which failed because it couldn't resolve the scipy dependency, which I already have installed. So I dove a little bit deeper and found

问题 I'm using C# .NET 4 with VS 2010. When Iterating over some paths, I'm running this line: files = Directory.GetFiles(path, searchPattern); I get an exception when the path is the documents and settings folder. How can I access it? And no, I don't want to skip the folder with a try and catch. I want to be able to access it somehow. Edit: I got a follow up question. As I told you, I'm iterating over the paths. Is there a way to use Environment.GetFolderPath but somehow idetifying the correct

问题 .load() is giving me trouble. I'm working on a section loader project and I just can't seem to fetch the file that I need. What I am trying to achieve : #sectionContainer is empty on document load, but on document ready it is 'filled' with Pages1.html . This is done by a JavaScript file sections.js .
