Hi @OlegOleg,
Can you post the output from the start of using atlas-create-jira-plugin? And also the output of
java -versionmvn -versionatlas-mvn -version
So we can try and reproduce this and see what’s happening?
Thanks,
James.
Hi, I changed my post to your request. Than you.
Hi @OlegOleg,
I have Java 1.8 and Java 11 and I can’t reproduce the issue. Looking at the first error
java.lang.reflect.InaccessibleObjectException: Unable to make protected void java.lang.Object.finalize() throws java.lang.Throwable accessible: module java.base does not “opens java.lang” to unnamed module @1753475d
I’d say the java 17 is enforcing the illegal access setting. Usually it’s just a warning in Java 11. You’re going to have to remove the Java 17 install to make things work. If this is your machine and you have root access there are a few options. I’m more familiar with Ubuntu, so you can try
update-java-alternatives --list
to see what is installed, and then set the default with the 1.8 version. For example, on my machine it’s
sudo update-java-alternatives --set /usr/lib/jvm/java-1.8.0-openjdk-amd64
You will also need to check if you have JAVA_HOME set
echo $JAVA_HOME
and see if that’s set to Java 1.8 home, which is the same as the update-java-alternatives --list provided. If it’s different, it’s probably set in .bash_profile or similar.
After all this, it still doesn’t work, you could remove Java 17.
Regards,
James.
- yes.
oem@oem-GL72-6QD:~$ update-java-alternatives --list

J2REDIR=“/usr/lib/jvm/jdk1.8.0_321/jre”
DERBY_HOME=“/usr/lib/jvm/jdk1.8.0_321/db”
and i don’t have .bash_profile
For reasons unknown to me, the /etc/profile file lacked these lines at the end
JAVA_HOME=/usr/lib/jvm/jdk1.7.0
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH
Hi @OlegOleg,
Okay, let’s clean some of this up so it’s more stable. I’d say you haven’t installed Java using apt so the environment is a little discombobulated.
I recommend restoring your /etc/profile back to the default to avoid issues on upgrade. You don’t have Java 1.7 installed, and shouldn’t be using it so please remove it and the other lines you added.
Same for /etc/environment. Remove the JAVA_HOME setting there as well.
Then create in your home directory the file .bash_aliases and into that have
JAVA_HOME=/usr/lib/jvm/jdk1.8.0_321 ; export JAVA_HOME
However …
If you want a really clean environment, and don’t require using Oracle Java and OpenJDK is good enough, then remove both Java 1.8 and Java 17, install open JDK with
sudo apt install openjdk-8-jdk
You’ll need to update the JAVA_HOME entry to the new location . update-java-alternatives --list should work correctly now and then provide the correct jvm to use.
James.
Hi James.
1.8 installed because it is indicated here Set up the Atlassian Plugin SDK and build a project.
Returned the /etc/profile to its original state and create .bash_aliases as you advised, thank you.
I fell into the same black hole as newbie Atlassian developer. Solved the Java problem:
:/etc$ whereis jvm
jvm: /usr/lib/jvm
:/etc$ JAVA_HOME=/usr/lib/jvm
:/etc$ export JAVA_HOME
:/etc$ PATH=$JAVA_HOME/bin:$PATH
:/etc$ export PATH
:/etc$ echo $JAVA_HOME
/usr/lib/jvm
:/etc$
but now I can’t download Atlassian SDK on Ubuntu using this method:
https://developer.atlassian.com/server/framework/atlassian-sdk/downloads/
update:
Success! just make sure to type sudo su before download
