windows - %M2% not working in system variable Path but in user variable Path only -


I'm setting up Maven and I need to set M2 and M2_Home. I have set them in the user variable in the Environment variable. And I was hoping to be able to run the path variable in the system variable in the ;% M2% I was able to run mvn --version but I could not However, if I resonate % pound% I can see that in the path there is % M2% and if I echo% M2% I

So I had this problem. Unless I created a path variable in the user variable and added % M2% to it, then Was the problem is solved and remove it from the path system variable. Now it is working. Does anyone know why this is working only in a specific way?

You have to look at the Windows source code to make sure what's going on, Not surprisingly, on the basis of my trial, it appears that system environment variables can only refer to other system environment variables, not user environment variables

Note that echo% PATH% should show the extended path you should not see % M2% .

This is because sometimes the system environment variables need to be expanded in situations where there is no user context if the user environment variable was included in the expansion of the system environment variable then it would be special case Should be considered as. It is also possible that it is considered preferred behavior so that the user's environment variables can not affect the interpretation of system variables unexpectedly, or environmental variables have been inherited in the process.

Add either % M2% to the user path or make the system M2 instead of the user environment variable.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
