问题 I am writing automated script for cloning GitHub source code to local machine. I failed after installing Git in my script, it asked for close/open powershell. So I am not able to clone code automatic after installing Git. Here is my code: iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1')) choco install -y git refreshenv Start-Sleep -Seconds 15 git clone --mirror https://${username}:${password}@$hostname/${username}/$Projectname.git D:\GitTemp -q 2>&1

问题 Is there a better way to print system properties from command line? As we can set the property e.g. java -D<name>=<value> //set a system property Without writing a class to do that? If not possible, why is it not possible/feasible/good to do that from the command line ? 回答1: You can use the -XshowSettings flag in the Hotspot JVM version 1.7 and up (not supported in 1.6): java -XshowSettings:properties -version OpenJDK has had support for this flag since late 2010.

问题 I am trying to use putenv stdlib function in a program that I am compiling with g++ including the flags and warnings -std=c++11 and -Wall -Wextra . The program can be as easy as the following: #include<stdlib.h> #include<iostream> int main(int argc, char *argv[]) { putenv("LD_LIBRARY_PATH=../Desktop/lib"); std::cout<<"hello\n"; return 0; } but I am getting this error warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings] .

问题 My question is not this question, because I have no discrepancy in java versions. The build on running 'ant clean all' is failing after I installed java 1.8.45 (both jdk and jre).

Your current Java version is: 1.8.0_45 TIP: If you are using eclipse you can configure a different JVM under Preferences->Java->Installed JREs.

问题 I'm using environment variables on my mac to store some sensitive credentials, and trying to access them through Node.

However, when I am trying to access this same variable in Node with process.env.VARIABLE_NAME and try to print it out on the console, I get an undefined. Other environment variables appear to be okay though. For
