FAQ - Lab 01: Setup

### Student-Facing Setup FAQ Doc #

Please take a look at the setup FAQ doc for additional setup assistance!

### I can’t find the plugins for IntelliJ! #

You likely installed the ultimate edition instead of the community edition. Make sure you have the community edition installed!

### When I try to push, I get the error “failed to push some refs” #

If you see a hint that says “Updates were rejected because the tip of your current branch was behind its remote counterpart”, then read this section of the Git WTFS.

### I set up SSH for GitHub, but I get the error “Connection timed out” #

SSH only works on secure (password-protected) networks. If you’re connected to CalVisitor or another an insecure network, git commands that try to talk to GitHub will fail.

To fix this, connect to eduroam or a secure WiFi network.

### On Gradescope, I’m missing required files #

First, make sure that you’ve pushed your code! You can check this by viewing your repository on GitHub.

Secondly, the expected file structure is

sp23-***
└── lab01
├── magic_word.txt
├── src
│   └── Arithmetic.java
└── tests
└── ArithmeticTest.java


Note that the files are inside the lab01 directory. If the files aren’t inside lab01, then the autograder won’t be able to find them.

If you’re sure you’ve done the above correctly, you may have two copies of your sp23-s* folder (with differing locations on your computer). Be sure that the one in your terminal and the one in IntelliJ match, otherwise your changes won’t be recorded! You can see the current working directory of your terminal by running pwd.

### I didn’t complete the git checkoff during my lab section #

Please use the asynchonrous checkoff form linked on Beacon to obtain a magic word!

### I’m using Mac, and after I install Java, it’s not showing up in IntelliJ or in JavaVirtualMachines#

See common mistakes doc linked on Ed, and/or come to lab and office hours!

### I’m using Mac, and I get “Unable to load Java Runtime Environment” #

Run brew reinstall java, and look for the command that starts sudo ln, right under “For the system wrappers to find this JDK…”. Copy-paste and run that command.

After this, your newly installed Java should appear in IntelliJ.
