rJava import not working in airflow - r

Question

I am trying to schedule some r script in airflow, I am using rJava library in my script. rJava and xlsx is working fine in R terminal, but not in airflow environment. I am getting this error,
libjvm.so: cannot open shared object file: No such file or directory
In my ~/.bashrc file,
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/bin/jar
export LD_LIBRARY_PATH=/usr/lib/jvm/java-8-openjdk-amd64/lib/amd64:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server
In my ~/.profile file,
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/bin/jar
export HADOOP_HOME='/home/ubuntu/spark-2.2.0-bin-hadoop2.7/hadoop-2.7.4'
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server:$LD_LIBRARY_PATH
In my /etc/environment,
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/bin/jar";
LD_LIBRARY_PATH="/usr/lib/jvm/java-8-openjdk-amd64/lib/amd64:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server";
Also, I tried to add this line in the top of my R script before importing rJava,
system('export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/bin/jar')
system('export LD_LIBRARY_PATH=/usr/lib/jvm/java-8-openjdk-amd64/lib/amd64:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server')
Even then I keep getting libjvm.so file missing error. But I can see that file in /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server
When I checked the log in airflow, the dag is running the script in Temporary script location: /tmp/airflowtmp7Ws3X2//tmp/airflowtmp7Ws3X2/nz-property-report6vTyGr
I think it is not picking the environment variables, getting this error,

Can anyone help me with using rJava in my R script in airflow?
EDIT: As requested, here is my DAG script,
import airflow
from airflow import DAG
from airflow.operators.bash_operator import BashOperator
#from airflow.models import DAG
from datetime import datetime
dag = DAG(
dag_id='property_report',
schedule_interval=None,
)
task = BashOperator(
task_id='report',
dag=dag,
bash_command="Rscript /home/ubuntu/airflow/dags/scripts/r-scripts/recreate_lastmonthreport_from_snapshotdata.R",
start_date=airflow.utils.dates.days_ago(1),
owner='airflow')

Just to help anyone looking for an answer for this. I just had to source ~/.bashrc in both screens running web server and scheduler separately and restart them. It picked up the env variables fine.
