Problems in Deploying and packaging applications #1

Open fmhwong opened 4 years ago

fmhwong commented 4 years ago

Step 2

Problem 1

$ export JAVA_HOME=$(/usr/lib/jvm/java-8-openjdk-amd64)
-bash: /usr/lib/jvm/java-8-openjdk-amd64: Is a directory

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.

[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project guide-getting-started: Compilation failure

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.

<logging traceSpecification="com.ibm.ws.microprofile.health.*=all" />

Step 5

Problem 10

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.

Problem 13

This link To access the application, visit the http://localhost:9080/system/properties URL. opens up http://localhost:9080/system/properties not a katacoda URL. It should be https://2886795310-9080-cykoria02.environments.katacoda.com/system/properties
