I get build errors when using mvn unleash:perform because it tries to use the default Java VM to build the release instead of the one pointed to with JAVA_HOME or the one which was used to start the maven-unleash-plugin.
With -Dunleash.releaseArgs="--debug=true" -X, I can see that the outer Maven uses Java 11 and the inner uses 8.
I tried to fix this with:
mvn unleash:perform -Dunleash.releaseEnvironment="JAVA_HOME=$JAVA_HOME" -X |& tee mvn.log
but that leads to an NPE:
Caused by: java.lang.NullPointerException
at com.itemis.maven.plugins.unleash.steps.actions.BuildProject.setupInvocationRequest (BuildProject.java:123)
at com.itemis.maven.plugins.unleash.steps.actions.BuildProject.execute (BuildProject.java:73)
Is changing the default VM in Windows my only option?
In my case, the culprit was in .mavenrc (Linux) or %USERPROFILE%\mavenrc_pre.cmd (Windows, also check %USERPROFILE%\mavenrc_pre.bat). There, JAVA_HOME was hardcoded to some specific path.
The fix is to a) only set JAVA_HOME when it has no value and b) to display a warning (with path) when the variable is set. That way, people can't get confused by some silent behavior.
Solution in .mavenrc:
if [[ -z "$JAVA_HOME" ]]; then
export JAVA_HOME=...
echo "~/.mavenrc: Setting JAVA_HOME to $JAVA_HOME"
fi
For %USERPROFILE%\mavenrc_pre.cmd, use:
if "%JAVA_HOME%"=="" (
set JAVA_HOME=...
echo %USERPROFILE%\mavenrc_pre.cmd: Setting JAVA_HOME to %JAVA_HOME%
)

SETTING UP TORCH UNDER LUA ON WINDOWS
--- Quick and dirty ---
Download and unzip the desired binary build from: https://github.com/hiili/WindowsTorch
Generate user.lua file in C:\Users\Name.zbstudio:
path.lua = [[C:\app\tools\torch\bin\luajit.exe]]
Move the C:\app\tools\torch\lua folder to C:\app\tools\torch\bin
--- Untested alternatives ---
Not tested, but I encourage you: https://github.com/torch/torch7/wiki/Windows#cmder
Maybe second best option is to build a virtual environment with linux
Note: More information on Torch can be found here

GET STARTED WITH LUA AND TORCH

I have used "rebar generate" to create the package and move package to the test pc for running.
But when running the common test suite, I don't know how to "-env ERL_LIBS XXX" with "ct_run" command.
How to correct it?
ct_run -dir /home/peter/gate-0.0.1.20/lib/gate-0.0.1.20/ct -suite gate_test_data_SUITE.erl -erl_args -- -env ERL_LIBS gate-0.0.1.20/lib
This variable also works for the environment. Have you tried running the command as ERL_LIBS gate-0.0.1.20/lib ct_run -dir /home/peter/gate-0.0.1.20/lib/gate-0.0.1.20/ct -suite gate_test_data_SUITE.erl ?
I have downloaded and compiled some Ros nodes from here (just to have more info). I am trying to launch the five ROS nodes with parameters using a launchfile that is taken from that repo.
After executing source catkin_ws/devel_isolated/setup.bash and executing roslaunch crab.launch(the launch file from the link above) the next error appears:
root#beaglebone:~# roslaunch crab.launch

I have reinstalled the packages as suggested in some other threats about similar problems.
I also have noticed that
1º- if I move all the executablesof the nodes to the folder src/<package>/, I'm able to execute roslaunch crab.launch. But I don´t want to leave it like that, not proper way to work ;)
Additional info:
2º- If I execute, for example, source devel_isolated/<package>/setup.bashand then roslaunch crab.launch, the package which I have just source-d works and executes... (while the other still don't)
3º- So I have source-d all the source devel_isolated/<package>/setup.bash and try again: no one worked this time.
This leads to think that the problems are due to ROS variable enviroment: if I make an export | grep ROSafter 2º, I can see that the package path appears in $ROS_PATH-s and the others are not there:
root#beaglebone:~# export | grep ROS
declare -x ROS_DISTRO="hydro"
declare -x ROS_ETC_DIR="/opt/ros/hydro/etc/ros"
declare -x ROS_MASTER_URI="http://localhost:11311"
declare -x ROS_PACKAGE_PATH="/root/catkin_ws/src/crab_msgs:/root/catkin_ws/src/joy:/root/catkin_ws

/install_isolated/stacks"
declare -x ROS_TEST_RESULTS_DIR="/root/catkin_ws/build_isolated/crab_imu/test_results"
Seems that 3º overwrites the source executed before..., meaning that in ROS_PACKAGE_PATHdoes not appear all he packages as they should.
I also have tried to force ROS_PACKAGE_PATHusing exportcommand, but it didn't work. So, I have to change more environment variables apart from that, but don't know which one...
So, I don't know if I diagnosis is correct and, if so, what should I do to correct this... Hope I have gathered enough info.
Thanks in advance!!

set the executable bit for files. most probably you need to set executable permissions for files.
chmod +x filename.
I am using
Ubuntu 12.04
Neo4j - Graph Database Kernel 2.0.0-M04
javac 1.7.0_25
java version "1.7.0_25
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Even though, I am using Oracle Java, I was getting warning:
"WARNING! You are using an unsupported Java runtime. Please use Oracle(R) Java(TM) Runtime Environment 7."
When I debug utils file in neo4j directory, I found a function with following comment:
# check if running JDK 6, warn if not
checkjvmcompatibility() {
$JAVACMD -version 2>&1 | egrep -q "Java HotSpot\\(TM\\) (64-Bit Server|Client) VM"
if [ $? -eq 1 ]
then
echo "WARNING! You are using an unsupported Java runtime. Please use Oracle(R) Java(TM) Runtime Environment 7."
else
$JAVACMD -version 2>&1 | egrep -q "java version \"1.7"
if [ $? -eq 1 ]
then
echo "WARNING! You are using an unsupported version of the Java runtime. Please use Oracle(R) Java(TM) Runtime Environment 7."
fi
fi
}
Some confusion :
comment of function shows that it is checking for java 6 but error message displayed use 'echo' shows that you are not using java run time 7.
So actually what Java is being expected by neo4j ?
I was using Oracle-Java-1.7 still it was throwing me error not using Oracle-Java1.7 .
Thanks
Amit Aggarwal
Neo4j 2.0 is supposed to run with Java 7 only. I guess the comment in the script is misleading. Please make JAVA_HOME points to the right directory. On linux this is not necessary valid if java -version shows version 7.
JAVA_HOME=/usr/lib/jvm/java-7-oracle
To check which version Neo4j is actually using run
grep "JVM information" -A 5 <neo4j_dir>/data/graph.db/messages.log
It is a bug, I got
ERROR! Neo4j cannot be started using java version 1.7.0_25.
...
http://localhost:7474/ is ready.
So it seems to start up OK, even though it gives this error message.
I am looking for functionality where we have a directory with some files in it.
Whenever any one makes a change in any of the files in the directory, jenkins shoukd trigger a build.
Is there any plugin or mathod for this functionality. Please advise.
Thanks in advance.
I have not tried it myself, but The FSTrigger plugin seems to do what you want:
FSTrigger provides polling mechanisms to monitor a file system and
trigger a build if a file or a set of files have changed.
If you can monitor the directory with a script, you can trigger the build with a HTTP GET, for example with wget or curl:
wget -O- $JENKINS_URL/job/JOBNAME/build
Although slightly related.. it seems like this issue was about monitoring static files on system.. however there are many version control systems for just this purpose.
I answered this in another post if you're using git to track changes on the files themselves:
#!/bin/bash
set -e
job_name="whatever"
JOB_URL="http://myserver:8080/job/${job_name}/"
FILTER_PATH="path/to/folder/to/monitor"
python_func="import json, sys
obj = json.loads(sys.stdin.read())
ch_list = obj['changeSet']['items']
_list = [ j['affectedPaths'] for j in ch_list ]
for outer in _list:
for inner in outer:
print inner
"
_affected_files=`curl --silent ${JOB_URL}${BUILD_NUMBER}'/api/json' | python -c "$python_func"`
if [ -z "`echo \"$_affected_files\" | grep \"${FILTER_PATH}\"`" ]; then
echo "[INFO] no changes detected in ${FILTER_PATH}"
exit 0
else
echo "[INFO] changed files detected: "
for a_file in `echo "$_affected_files" | grep "${FILTER_PATH}"`; do
echo " $a_file"
done;
fi;
You can add the check directly to the top of the job's exec shell, and it will exit 0 if no changes detected.. Hence, you can always poll the top level of the repo for check-in's to trigger a build. And only complete a build if the files in question change.
