How to run azure-cli commands from java - java

I have azure-cli installed in my mac and I can successfully execute all azure commands from cli. I want to do the same from a java application. I have seen examples of using REST endpoints and azure-sdk-for-java. But what I want is to execute the azure-cli commands directly from java.
I tried running 'azure login' from a java program, but I got the following error.
Cannot run program "azure": error=2, No such file or directory

The problem is in a lack of your PATH variable. If you want to enjoy the same "find the command" capabilities that you have on the command line, you need to set it somehow within your Java program: import the PATH variable from the environment, set it within the code you're writing, or whatever mixture covers your needs.
Giving the absolute (full) path is the surest way, but you may not want to read such long command names in your source codes.

#harshithabt Per my experience, the issue was caused by the command azure could not be searched in the directories listed in PATH. There are two ways to solve the issue for running commands in Java, please see below.
Setting up the environment variable PATH for the current shell session or the configuration files ~/.profile(or ~/.bashrc).
If you command export PATH=<your-node-path>/bin:$PATH in a shell session, you only run the Java program with azure command in the current shell session, even run via the Java IDE which must be opened in the current shell session (it means you should open Eclipse via command <your-ide-path>/eclipse).
If you configure the files ~/.profile or ~/bashrc to add the node runtime as below, please make sure the configuration files have been reloaded via command source ~/.profile in a current session or restart sessions via logout & login or reboot.
A simple way is that adding the command links into the dirs listed in PATH, such as /bin. You just need to run the commands below.
sudo ln -s /bin/node /bin/node
sudo ln -s /bin/azure /bin/azure
Then you can run azure-cli command from Java successfully.

IntelliJ Cannot Open Local Terminal - Failed to start powershell [duplicate]

I have been attempting to run powershell as my terminal on windows in pycharm, so I did the following:
However, when I try this, it says that it cannot execute my scripts, and hence I get the following error: SecurityError and the Fully Qualified Id is : UnAuthorizedAccess.
This arises from the fact that pycharm's terminal cannot execute my Powershell_profile.ps1 profile file.
How can I successfully run Pycharm's terminal with Powershell?
What I have tried so far, is going into my main powershell directory as in %windir%/system32/WindowsPowerShell/1.0/profile.ps1, and then change it to include the following:
Set-ExecutionPolicy Unrestricted
However, this does not help, and I get the same error when I try to open of pycharm's terminal.
I have also tried to run pycharm as Admin, however this does not solve the problem either, and I get the same aforementioned error.
I've replaced cmd.exe with powershell.exe in a simpler way and hope it can help.
I'm using webstorm2017 and Win10 os.
1.Find the exact location of powershell.exe.In mine and I believe in most computers the location would be C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe.Copy the whole path into your clipboard.
2.In your IDE open File=>Setting=>Tools=>Terminal, and paste the path into "Shell path" blank.
3.Restart the IDE and everything would be ok.
Set-ExecutionPolicy Unrestricted -Scope CurrentUser
I updated the powershell.exe path in IntelliJ -> Settings -> Terminal
Opened a powershell instance in Admin mode.
Executed Set-ExecutionPolicy Unrestricted -Scope CurrentUser
Restarted IntelliJ and the issue was solved.
Step 3 is from ebelanger's answer.
Browse to the PowerShell executable, right-click, run as administrator.
From the prompt, use the same command you tried:
Set-ExecutionPolicy Unrestricted
Once that is done, close PowerShell, and attempt to use it again from your application.
Note:
You can't set the execution policy from a script, as the default execution policy prevents you from running scripts. (even if it's the profile script - still a script)
In PyCharm
File->Settings->Tools->Terminal
Shell path:
"powershell.exe -ExecutionPolicy Bypass"
Then restart PyCharm
In the Default Shell TextBox you can append the execution policy command line option like so:
powershell.exe -Executionpolicy Unrestricted
If you're running on Windows 8 x64 then running both the commands below may help. It worked for me.
Set-ExecutionPolicy Unrestricted
start-job { Set-ExecutionPolicy Unrestricted -Force } -RunAs32
Credit to a comment found here:
Powershell on Windows 7: Set-ExecutionPolicy for regular users
As mentioned in other answers, if after setting powershell.exe as your terimal in IntelliJ → Settings → Tools → Terminal → Shell path it throws UnAuthorizedAccess errors, normal way to solve this is to alter execution policy:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Note that Unrestricted level is the least secure of all, and you're usually can go with RemoteSigned in order to disable unsigned scripts downloaded from the web until you manually remove Internet or Intranet Zone.Identifier from them, usually with Unlock button in file properties.
However, you may run to an occasion when you're not able to change execution policy. Usually that's because of corporate security settings in Active Directory. In PowerShell, that corresponds to scopes MachinePolicy and UserPolicy. A primary symptom of this situation is the following message:
Set-ExecutionPolicy : Windows PowerShell updated your execution policy
successfully, but the setting is overridden by a policy defined at a
more specific scope. Due to the override, your shell will retain its
current effective execution policy of AllSigned. Type
"Get-ExecutionPolicy -List" to view your execution policy settings.
For more information please see "Get-Help Set-ExecutionPolicy".
You can't set execution policies at this scopes with PowerShell or gpedit.msc. Attempts to change this settings directly in registry is also ineffective: they're applied on restart or login, but at the same time they're being re-imported from Active Directory. However, while you won't be able to run arbitrary PowerShell scripts all around, for profiles and other local scripts that's only modified manually there's still a solution:
Run the following command in PowerShell to create ceritificate files root.pvk and root.cer - it will ask you to define and then confirm password to the certificate:
makecert -n "CN=PowerShell Local Certificate Root" -a sha1 -eku 1.3.6.1.5.5.7.3.3 -r -sv root.pvk root.cer -ss Root -sr localMachine
In the same folder, run the following command to import generated certificate files as your self-signed certificate - it will ask for the password you're defined above:
makecert -pe -n "CN=PowerShell User" -ss MY -a sha1 -eku 1.3.6.1.5.5.7.3.3 -iv root.pvk -ic root.cer
Sign your profile script with the following command:
Set-AuthenticodeSignature "[script path]" #(Get-ChildItem cert:\CurrentUser\My -codesign)[0]
When running a script signed with self-ceritificate for the first time, PowerShell will ask you about trusting the certificate like this:
The file [script path] is published by CN=PowerShell User. This publisher is not trusted on your system. Only run scripts from trusted publishers.
[V] Never run [D] Do not run [R] Run once [A] Always run [?] Help (default is "D")
Answer A to always run self-signed certificates.
Now your profile script won't cause any errors. However, note that signing a certificate adds a signature block in the end of your script containing its hash. If you're about to modify the script, remove that block and, after you're done with editing the script, sign it again by repeating step 3.
Specify the shell that will run by default. Here are some examples of different shells:
Bash: /bin/bash
Z shell: /bin/zsh
Bash for Windows: bash.exe
WSL: wsl.exe
PowerShell: powershell
Command Prompt: cmd.exe
Cygwin: "C:\cygwin\bin\bash.exe" --login -i

As of this writing (2018-9-20), there is now a PowerShell plugin available here.
I have installed v1.1 in PyCharm v2018.2.3 (Professional), and it seems to work like a charm, no pun intended.
This plugin provides Intellisense-type support of PS1 scripts, as well as an integrated PowerShell terminal. In order to open the terminal, go to Tools > PowerShell Console...
There appears to be no need to muck about with any kinds of settings or permissions in order to get it to work. It Just Works.
You only need to write powershell in the Shell path input, just like in the image, also you can see jetBrains documentation and configure any shell you want.
powershell configuration
For WebStorm and PowerShell 6+ on Windows 10.
Just follow this screenshot and change the default cmd.exe to pwsh.exe from settings. Finally restart the ide. Done!

not able to execute shell script

I've scenario where I execute my java code using shell script.
When I run that shell script from autosys, it runs fine. But when I try to run it manually from linux box, it says Java not found error.
And when I check manually java version in linux box, using java -version it says java not there.
How its possible that, same shell script is triggered by Autosys but not manually ?
May I know please, what type of configuration is this ? I'm I missing anything ?
It is possible that the Java could be installed for the autosys user only in which case it will not be accessible by another user.
The autosys user could have had some PATH variable (perhaps in the profile) that points to the Java binary, which might not be present in your current user. You might want to check your ~/.profile file (or) ~/.bashrc, ~/.bash_profile to see if there is PATH variable.
To debug, just include which java in your shell script and check the output when the autosys runs it. This will give you the path of the java binary.
(or) Simply login as your autosys user and execute the same script.
May be, you might also be missing some bootstrap commands before executing your script (like export PATH etc).

unable to launch HBase shell

I am able to get localhost:16010 running. But, somehow the Hbase shell is not launching when I use :
01HW993798:bin tcssig$ cd /Users/tcssig/Downloads/hbase-1.0.3/bin
01HW993798:bin tcssig$ hbase shell
-bash: hbase: command not found
When I directly launch Hbase Unix executable, it generates the below error log.
Error: JAVA_HOME is not set
Although I have set it. After this only, the localhost:16010 is running.
NOTE : I know there is one similar question, but no relevant answers are present there.
Using this I am able to invoke the command, but now it gives the error :
./hbase: line 403: /Users/tcssig/Downloads/hbase-
1.0.3/bin/JAVA_HOME:/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Cont``ents/Home/bin/java: No such file or directory
Although I have java file there.
Your hbase invocation should be like this:
cd /Users/tcssig/Downloads/hbase-1.0.3/bin
./hbase shell [Note the ./]
When you just type hbase shell linux searches for hbase executable in all directories included in PATH environment variable. Since above bin directory is not included it errors out.
Alternatively you can also update your path variable, based on linux distribution, the command to do that may vary. It should be something like:
export PATH=/Users/tcssig/Downloads/hbase-1.0.3/bin:$PATH
Put this command in your .bashrc or .bash_profile and then source this file. That way the bin directory is now included in PATH and hbase command is available.
Go into $HBASE_HOME/bin path, and try:
./hbase shell

run java exec command, always need full absolute path to the application?

Environment: mac
Precondition: I already configured 'adb' full path to my bash_profile. and when I tried type 'adb' in my terminal, it is working.
But, I tried to exec 'adb' command from java, 'adb' is not working, instead I need to pass the full adb path to make it work.
I guess this is probably something to do with the bash_profile setting, anyone know the exact reason for this issue?
Runtime.getRuntime().exec() runs /bin/sh -c <command>. If this is or points to a bash shell on your system: A non-interactive bash does not read .bash_profile unless explicitly (--login) told to do so.
From the documentation:
When Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
It's a little convoluted, but non-interactive, non-login bash instances don't read the profile files.
Your path settings does not get picked up by the subshell (which is actually /bin/sh which might not even be bash at all).
If you want, you can add the path to adb system wide by adding an appropriate entry to to /etc/paths.d.

It can't process the by clicking the spark-shell windows command script. What i do?

In the Process of installing spark 1.0.0 by double clicking the bin/spark-shell windows command script file. Then opened one command prompt file and then immediately closed it self only. Are there any commands required to run this. Could you please tell me step by step process.
First of all, you have to open a terminal. Theorically, you at least have the following on your machine :
cmd (for sure)
powershell (maybe not, if you're using Vista or less).
From there, you have two options :
if you added path_to_spark_folder\bin to your PATH variable (see there for more informations), you can run spark-shell as soon as the console is opened
if you didn't, you'll have to go to path_to_spark_folder\bin yourself, using the cd command.
You now can run spark-shell.
