The directory shouldn't be in $( )
Problem 2
After added <feature>mpHealth-2.0</feature> into server.xml and ran mvn package, Liberty didn't detect server.xml has changed and therefore /health still returned 404. I had to restart Liberty to get it working.
Step 3
Problem 3
Ran these two commands
$ cd src/main/java/io/openliberty/sample/system
$ touch SystemReadinessCheck.java
and clicked the link to open SystemReadinessCheck.java. No file was open in the editor.
I have to manually navigate to the file to open it. Pasted the code.
Problem 4
Ran the this command
$ touch SystemLivenessCheck.java
Where is the link to open it? Where is the content to copy and paste?
Problem 5
Instruction says to ran mvn compileand got this error
[ERROR] The goal you specified requires a project to execute but there is no POM in this directory (/root/guide-getting-started/start/src/main/java/io/openliberty/sample/system). Please verify you invoked Maven from the correct directory. -> [Help 1]
This was because I was still at /root/guide-getting-started/start/src/main/java/io/openliberty/sample/system
The instruction should have a cd back to start
Problem 6
I changed directory back to /root/guide-getting-started/start and ran mvn compile. I got compile error.

Step 4
Problem 7
The link could not open server.xml
Problem 8
The content of server.xml in the instructions was different from what I have in the actual file.
Problem 9
It doesn't have a snippet for me to copy and paste the logging element.
It didn't tell users to stop the server first before trying mvn liberty:start and mvn liberty:stop
Step 6
Problem 11
Since I have compile errors from previous steps, I started off from a new session and fast forwarded to step 6.
