Failing to set up Openmrs SDK on Linux Os

Development
1

Am setting up openmrs sdk on my Linux os but each time i run this (mvn org.openmrs.maven.plugins:openmrs-sdk-maven-plugin:setup-sdk ) command it keeps on throwing this exception. Have tried to follow several tutorials and documentations on google but have not yet achieved success. I need help

@kdaud

did you consider this The JAVA_HOME environment variable is not defined correctly from your log ?

3

Your Java Environment is not correctly configured to support applications.

4

@tendomart I understood the error but failing to resolve it.Have tried to edit ./bashrc script by adding
(JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"
export JAVA_HOME
export PATH=$PATH:$JAVA_HOME/bin)
as most documentation suggests but its not working out.

5

Give all the details of what you’re doing…We cannot guess your system specs.

Plus what do you get when you type the following in Terminal ?

javac -version

java -version

mvn -v

6

java -version:
openjdk version “1.8.0_222” OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10) OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

javac -version:
javac 1.8.0_222

mvn -v:
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
I installed maven and i can see it in maven: /etc/maven /usr/share/maven directory

@kdaud could you try using some other sub version of jdk 1.18.0 ,may be you can try it with 1.8.0_201?

8

@kdaud try restarting your machine.

What do you get when you run

sudo update-alternatives --config java

and sudo update-alternatives --config javac

9

sudo update-alternatives --config java gives
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java Nothing to configure.

sudo update-alternatives --config java gives
There is only one alternative in link group javac (providing /usr/bin/javac): /usr/lib/jvm/java-8-openjdk-amd64/bin/javac Nothing to configure.

Can this be of help?

find /usr/lib/jvm/java-1.x.x-openjdk

vim /etc/profile

Prepend sudo if logged in as not-privileged user, ie. sudo vim
Press 'i' to get in insert mode

add:

export JAVA_HOME="path that you found"

export PATH=$JAVA_HOME/bin:$PATH

logout and login again, reboot, or use source /etc/profile to apply changes immediately in your current shell

Have tried several times editing /etc/profile but the error persists. Uninstalling openjdk and giving a try to oracle jdk is now am trying to find out whether would yield success

12

Ok. Waiting for the outcome.

13

@kdaud I don’t know what you are using. But for starters you can install nano. In the command line type in

sudo apt-get update

then

sudo apt-get install nano

then

sudo nano /etc/profile

an editor will open and paste these lines after the last fi

export JAVA_HOME
JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
PATH=$PATH:$JAVA_HOME
export PATH 

Press Ctrl and O,
press Enter,
Press Ctlr and X

paste this in the commandline   source /etc/profile

exit and restart your machine

let me know what you get. 

I would not advise you to go to oracle, just stick to open jdk, Don't easily give up the fight. :)

@irenyak1, I find it fun using gedit or nano. So I use them

15

@kdaud yes go ahead and follow the steps

which step have you reached on this?are you able to install the sdk successfully?

I finally figured out the error after exporting the JAVA_HOME and PATH in .bashrc . Exporting it into /etc/profile didn’t work out.
I added export JAVA_HOME=/usr/lib/java/jdk1.8.0_221
export PATH="$PATH:$JAVA_HOME/bin" in .bashrc script and the issue was resolved
