cannot start cas-overlay-template on windows - missing \etc\cas\thekeystore

I am trying to run https://github.com/apereo/cas-overlay-template on Windows 11 and JDK 11 (Eclipse Adoptium 11.0.16.1), using the 6.5 branch. I have ran the "createKeystore" and "copyCasConfiguration" gradle tasks using gradlew.bat, and it created the files below:
c:/etc/cas/cas.crt
c:/etc/cas/thekeystore
c:/etc/cas/config/cas.properties
c:/etc/cas/config/log4j2.xml
when I tried to run "gradlew.bat run", it hit the following error:

I believe this is due to Gradle thinking its running inside a Unix environment instead of a Windows one. Any changes I make to the c:/etc/cas/config/cas.properties file is ignored, which makes me believe that its looking elsewhere for the cas folder (not c:/etc/cas). Anyone got any ideas?

You can change the keystore location in spring config. You can pass the property either in cas.properties or with command line flags or ENV. Two examples:
Example: absolute windwos path
server.ssl.key-store=D:/dev/cas/etc/theKeystore.jks
Example: relative path
server.ssl.key-store=file:etc/cas/thekeystore
By the way, you can also change the location of the cas.properties file with the cas.standalone.configurationDirectory parameter. This is how I usually work in a local environment on Windows:
java -jar build/libs/cas.war --cas.standalone.configurationDirectory=etc/cas/config --debug

Anyone got any ideas?
Please read:
https://apereo.github.io/cas/6.5.x/installation/Troubleshooting-Guide.html#review-logs
CAS server logs are the best resource for determining the root cause of the problem, provided you have configured the appropriate log levels. Specifically you want to make sure DEBUG levels are turned on the org.apereo package in the log configuration
You could consider moving the configuration inside the CAS build itself in an application.yml file, instead of keeping it outside.
https://apereo.github.io/cas/6.5.x/configuration/Configuration-Server-Management-Standalone.html

Try switching from tomcat to jetty as an embedded servlet server. It seems to have better windows support, and properly looks for c:\etc\cas\thekeystore.
To do that just replace -tomcat with -jetty as appServer in the gradle.properties file.
There might be a way to teach tomcat to look at the right place, but I didn't found it. The server.ssl.key-store setting didn't had any effect.

Unable to create tempDir. java.io.tmpdir is set to /tmp

Try any of the following:
1) Change permissions of /tmp to give access to your user.
chmod -R 777 /tmp
make you sure you run above command with sudo access (root)
2) add the user who is to the sudo group.

In case you are getting this issue while deploying Spring boot application in Kubernetes, one of configuration worth checking is readOnlyRootFilesystem. It must be set to false until you are trying to intentionally run read only containers.
It can be used in deployment config as following:
template:
metadata:
labels:
app: hello
spec:
containers:
- name: hello
image: hello-world
securityContext:
runAsUser: 1000
readOnlyRootFilesystem: false ## this should not be true

For ones who are getting same exception while running from Intellij IDEA when providing env variables as part of run/debug configuration:
please look if "Include parent environment variables" is checked

your application user probably does not have sufficient permissions to crate anything in /tmp directory ... see last message Caused by: java.io.IOException: Read-only file system

The most likely explanation for this is that the root filesystem is full. It was the issue for me.

One reason for this error is that you not include system environments variables. Maybe you try to define a new configuration with different system variables that are defined in your java IDE and you disable default environments variable.
Please enable checkbox:
Run/Debug Configuration -> select your configuration -> press on the environment variables -> check Include system environment variables (as in the picture added above).
Keep in mind that you need to check if you have added the path of the Temp file in the system variables.

Thank you all..

you can add openejb.system.apps=false in conf/system.properties or just export CATALINA_TMPDIR to a "new tmp dir value"

I'm trying using my local user, root user, changing ports (ie: run 8080), start instead of run, and it always throw the same exception.
By the way, port 9000 is not in use by another application.
Anyone has any clue?
I'm using Ubuntu 12.04 LTS, and Play Framework 2.2.6.
Thanks.

The error is that your port is being used by another process.
In a UNIX machine the command lsof -i:9000 will give the processes that are using the port.
As you have noted correctly processes with root permissions can be hidden if you use the terminal not as root

This is likely due to using Java 8 rather than Java 7. Even though you have installed Java 7 - perhaps you still have JAVA_HOME set to Java 8?
