问题 I have a class with the following code: Process process = null; try { process = Runtime.getRuntime().exec("gs -version"); System.out.println(process.toString()); } catch (Exception e1) { e1.printStackTrace(); } finally { process.destroy(); } I can run "gs -version" on my command line and get: GPL Ghostscript 8.71 (2010-02-10) Copyright (C) 2010 Artifex Software, Inc. All rights reserved. So I know I have the path at least set somewhere. I can run that class from command line and it works. But

问题 I have Eclipse Helios with a java program set up. I'm attempting to create two environment variables ReportingManagerHome=C:\rp ReportingManagerConfig=${ReportingManagerHome}\config I then run my program with System.out.println(System.getenv("ReportingManagerConfig")); Eclipse doesn't even call the java compiler. It throws up a pop up window with the error that environment variable ReportingManagerHome is not defined. I understand that since the java compiler has yet to be called, technically

问题 I am trying to run an already existing chunk of R code in a sandbox-ed fashion, by saving the global environment (containing functions and data) to a file, then loading it into a new environment (not the global environment) and evaluating a function call within that environment. However, I'm running into trouble with functions calling other functions in the environment. Here's an example: f1 <- function(x) x*2 f2 <- function(y) f1(y) + 1 save(list=ls(), file="env.RData") rm(list=ls()) jobenv

问题 We are using Tesseract OCR Java library called Tess4J. It works fine if run as a standalone application. It needs a variable called TESSDATA_PREFIX which contains the tessdata config and other charset related files. It also runs fine with embedded Tomcat 6 server in eclipse. I had set TESSDATA_PREFIX as an environment variable by using the launch configuration. But when I package everything into a WAR and drop it in deploy directory of tomcat, the environment variable does not seem to be

问题 I've tried looking into process builder, but I'm not sure how to source the bash environment into the process. For example I'm using the following to launch my process: Process p = new ProcessBuilder(args).start(); InputStream is = p.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); And I'd like my standard shell environment (from /etc/profile, .bashrc, etc.) sourced to the process. Sorry if I'm not using the right terms - still

问题 I know that virtualenv, if not passed the --no-site-packages argument when creating a new virtual environment, will link the packages in /usr/local/lib/python2.7/site-packages (for Python 2.7) with a newly-created virtual environment. On Ubuntu 12.04 LTS, I have three locations where Python 2.7 packages can be installed (using the default, Ubuntu-supplied Python 2.7 installation): /usr/lib/python2.7/dist-packages : this has my global installation of ipython, scipy, numpy, matplotlib –

问题 I am attempting to write a pipeline script to use with Jenkins 2.0 to replicate our existing build. This original build used the envInject plugin to read a Java properties file, but I can't see how to do this from the pipeline Groovy script. I have Googled and found the following, but it doesn't work (FileNotFoundException): Properties props = new Properties() File propsFile = new File('./Builder/project.properties') props.load(propsFile.newDataInputStream()) Thanks! 回答1: I just fought with

问题 I want to extend core Array class with simple method: class Array def to_hash result = Hash.new self.each { |a| result[a] = '' } result end end I put array.rb into lib/core_ext and tried to require it in application.rb by config.autoload_paths += %W(#{config.root}/lib) config.autoload_paths += Dir["#{config.root}/lib/**/"] But still get undefined method 'to_hash' for ["var1", "var2", "var3"]:Array if tried to use it in model method. Of course I rebooted the server after code changes. 回答1:
