I previously asked a similar question with regards to cloud9, but I am now trying to do the same project in parallel on my windows 10 machine because I will not have internet access to use cloud9. I am trying to set up the configuration in preparation for following Daniel Kehoe's learn-rails tutorial book, but I am having trouble setting up the environment variables. The book seems to explain how to do it on Mac but I can not find the file in the atom editor. the book says to type the command:
atom ~/.bash_profile
However this just creates a new file that is not part of my rails app project directory. i have also tried
atom ~/.bashrc
which is the alternative but with the same result. It just creates a file unrelated to my project. The file is supposed to already exist somewhere.
I am supposed to put the environment variables into a file called ".bashrc" but I don't know where to find this file as it is hidden. How can I locate and open this file with Atom text editor?
.bashrc , .bash_profile are used in unix based operating systems for the terminal. In windows you set environment variables differently. In windows 10, search for environment variables in start menu, and select Edit the system environment variables and set them from there.
PS: You can have .bashrc if you have installed something like git bash, cygwin bash or bash for windows 10 or something else. And all 3 handle .bashrc differently.
Typing echo ~ in the Git Bash terminal will tell you where that folder is which contains the .bashrc file
I am trying to set my environment variables to
$env:DEBUG="*,-babel"
But I cant figure out where to use this setting in the Atom editor
To make the shell's environment variables available to Atom, install following two small atom packages:
env-from-shell
auto-run
env-from-shell settings: enter comma delimited list of needed environment variables in it's settings panel. Check off auto-run box.
auto-run settings: if not already present, enter env-from-shell:copy in it's settings panel. A benefit of the env-from-shell package is no external configuration files have to be moved from directory to directory as projects change.
Try setting
process.env.DEBUG = "*,-babel"
in your (new) $HOME/.atom/init.coffee init file.
(Your directory may vary, see your process.env.ATOM_HOME.)
I've put in an embarrassing amount of time reading threads here and elsewhere, I cannot compile HelloWorldApp.java
Using Windows 7
the location of the script is C:\Users\Phil\Desktop
the location of javac is C:\Program Files\Java\jdk1.8.0_77\bin
In Environment Variables, in both User and System Variables, I have clicked NEW, and given the "Variable Name" as javac and "Variable Value" as `
C:\Program Files\Java\jdk1.8.0_77\bin;
`
I have tried to make this work based on the 2 different ways here (to no avail): https://docs.oracle.com/javase/tutorial/getStarted/problems/
I am failing to set a path, or tell computer where to find it from within cmd. What am I doing wrong?
just you have to do set temporary path set path=C:\Program Files\Java\jdk1.7.0_45;
or
change your Environment variable path
to
variable name=%path%
variable value:\Program Files\Java\jdk1.7.0_45;
then open cmd and run javac command to check
Okay, so I have solved my problem:
In Environment Variables, the "Variable Name" must be: PATH
The Variable value is: C:\Program Files\Java\jdk1.8.0_77\bin
Now It works!
When I run targets on ant it says it is unable to locate the variable I passed to it.
Config for environment variables :
in build.xml
<property environment="Env"/>
but I am unable to find the parameter defined parameter with
${Env.CATALINA_HOME}
where in the .bash_profile
export CATALINA_HOME=/Users/olgunkaya/development/apache-tomcat-7.0.34
and export PATH=${PATH}:$CATALINA_HOME
What can I do to achive this ?
Before you run ant, check to see if CATALINA_HOME is actually defined as an environment variable. I bet you'll find it isn't. Ant doesn't read your .profile or .bash_profile before starting, so if it's not already defined in your environment, Ant won't see it.
As you've seen opening a terminal window on a Mac doesn't necessarily guarantee that the .bash_profile file is executed. Try setting up these environment variables in .bashrc file instead.
Or, you can force .bash_profile to run by setting it as the Startup file in Terminal. Select File->Preferences from the menu, go to the Shell tab, select your default shell, and then click the Run Command checkbox and put .bash_profile in there. That will guarantee that .bash_profile is executed with each new terminal window.
I had a similar problem when referencing a custom variable, which was definitely defined in the shell spawning ant.
The solution was to EXPORT the variable when defined (in ~/.profile), so the shell would pass it to its children.
I have been trying to install Maven v 3.0.4 on my machine win 7 for the first time.I have a problem setting the path environment System variable I have the following 4 entries :
PATH
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04;C:\Program Files\apache-maven-3.0.4\bin;M2_HOME;%M2%
M2_HOME
C:\Program Files\apache-maven-3.0.4\bin
M2
%M2_HOME%\bin
JAVA_HOME
C:\Program Files\Java\jdk1.7.0_04\bin
when I do mvn --version
I get the error:
JAVA_HOME not found in your environment, please set the JAVA_HOME variable in your environment to match the location of your java installation
The java -version displays the java version fine,
what am I doing so horribly wrong? Is the PATH ok?
Help appreciated, thanks.
It is only necessary to set the path to the Maven binary and to the JDK correctly:
set PATH %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jdk1.7.0_04\bin;C:\Program Files\apache-maven-3.0.4\bin
Furthermore you need to set the JAVA_HOME correctly which is done under windows like this:
SET JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04
Be aware of setting JAVA_HOME to the root of the installed JDK and not to bin folder it.
The settings of M2 and M2_HOME is not necessary.
from command prompt run the following
set M2_HOME= C:\Program Files\apache-maven-3.0.4
set PATH=%PATH%;%M2_HOME%\bin
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04
set PATH=%PATH%;%JAVA_HOME%\bin
cmd.exe
mvn -version
The environmental variables should point to the installation directory of each program respectively, and their corresponding bin folders should be added to the PATH:
Make sure that your JAVA_HOME points to the C:\Program Files\Java\jdk1.7.0_04 (or whatever directory you have installed your JDK to).
Add the %JAVA_HOME%\bin folder to your PATH (e.g. by replacing the part with C:\Program Files\Java\jdk1.7.0_04). Make sure that you use ; to separate different path components.
Likewise, the M2_HOME variable should be assigned Maven's installation directory, e.g. C:\Program Files\apache-maven-3.0.4 and you should add %M2_HOME%\binto the PATH (the part with C:\Program Files\apache-maven-3.0.4\bin;M2_HOME;%M2% can be removed.
The advantage of adding the environmental variables %JAVA_HOME%\bin and %M2_HOME%\bin on the path rather than the fully qualified path is that it will be easy to update Java and Maven (or to have several versions installed in parallell). All you need to do is to update the environmental variable, and the PATH variable will fallow automatically.
I ran into the same issue as the original poster. I checked, double checked, and triple checked everything to conform to what everyone has (correctly) indicated the setup needs to be. I still got the same error. In the end, I ran SET JAVA_HOME=C:\Program Files\Java\jdk1.7.0_45 from the command line and then ran the mvn command and viola.
So, for what ever reason, pss's suggestion did the trick. Obviously, this doesn't really change what everyone else said, because that's exactly what my environment variables look like...just had to hit the JAVA_HOME from the command line.
Oddness.
I followed all the steps but it was not working for me. But as soon i have set the JAVA_HOME Path, in Command prompt just type:
C:>SET JAVA_HOME=C:\Program Files (x86)\Java\jdk1.8.0_91
It is working fine in fraction of seconds. Thanks Everyone.
I faced the same problem on local installation. I tried out all the suggested methods including the SET method but that didn't work for me. In the end, I had to manually add another environment variable to the system, and then after that
mvn -v
gave the appropriate response:
Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T04:57:37-07:00)
Maven home: C:\Program Files (x86)\apache-maven-3.3.3-bin\apache-maven-3.3.3\bin\..

If, like me, you are running mvn -version from the command prompt, and then adding any missing environment variables from the GUI, it is possible that you just have to reload the command prompt after adding the environment variables.
Just exit and run cmd.exe
You need to make a variable of name JAVA_HOME in your Environment and set its value as path to jdk.
Right click on My Computer/ This PC -> Properties
Choose Advance system settings
Open Environment variables
Under System variables click on New... button and give the name
as JAVA_HOME and value as c:/path/to/jdk
Version that I always use. Double click and you get the maven up and running
#echo off
title Maven 3.0.5
set JAVA_HOME=C:\Users\hutingung\Development\jdk\jdk1.6.0_33
set MAVEN_OPTS=-Xmx1024m -Xms512m -XX:MaxPermSize=192m -Dfile.encoding=utf-8
set MAVEN_HOME=C:\Users\hutingung\Development\tools\apache-maven-3.0.5\bin
set PATH=%MAVEN_HOME%;%JAVA_HOME%\bin;%PATH%
#cmd /k
Yes, Appending that path C:\programfiles\maven\bin to path variable in system variables is enough, it will work. No need to add user variables.
