I got following error when I execute./gradlew build [Any of them; all , core etc.]

What is your Java JDK installation?

[zhuhuilong]

[tverbele]

What is the output of echo $JAVA_HOME, this should point to the java installation dir, something like /usr/lib/jvm/java-8-openjdk

[khalidpandit]

/dianne$ echo $JAVA_HOME /usr

my jdk version is 1.8 and i am getting the same error..please help me with this

[tverbele]

I think your $JAVA_HOME is pointing to a wrong directory. This should be the home dir of your Java installation instead of just /usr. What is the output of whereis java?

[khalidpandit]

do i need to keep it in /usr/lib or /usr/share

[tverbele]

It seems your JAVA_HOME is configured wrongly. Try export JAVA_HOME=/usr/lib/jvm/java-8-oracle

[khalidpandit]

i changed theJAVA_HOME but it still hangs on 87%

[tverbele]

This is actually a successful run, since we integrated launching into the build system for easy testing, the 'build' will only reach 100% once you again stop the run... You can also use the :tools:export.all tasks and then manually launch the create .jar file using java -jar

[khalidpandit]

this does not show the ui builder. how can i get ui builder

[tverbele]

What does it show when you point your browser to localhost:8080?

What is the list of bundles if you type lb in the window where the buid runs?

[khalidpandit]

[tverbele]

You are missing quite some of the required bundles in this launch configuration. Did you change any of the default bndrun files?

[khalidpandit]

basically this is the error while ./gradlew build

[khalidpandit]

i did not change any bndrun file

[tverbele]

Ah ok, the native build has failed linking due to missing gfortran library. Install using sudo apt-get install gfortran and try to build again?

[khalidpandit]

sudo apt-get install gfortran does not work..is there any other way of installing gfortran

[tverbele]

Strainge, the gfortran package should be available on your ubuntu system (https://packages.ubuntu.com/trusty/gfortran). What error do you get? Maybe do an sudo apt-get update first?

[khalidpandit]

i installed gfortran but still ./gradlew build fails .... what should i do

[eliasdc]

It seems your computer is missing a lot of general development dependencies. In our getting started guide we state that the software requires the following dependencies for compiling from source:

• Java JDK (minimum version 1.8), i.e. Oracle JDK or OpenJDK
• OpenMP
• GNU GCC
• GNU Make
• CMake
• Git
• gfortran

In the latest screenshot it states cmake: command not found which indicates not all dependencies are installed on your system. For this specific error the following should help you progress:

sudo apt-get update
sudo apt-get install cmake build-essential

[khalidpandit]

i installed the cmake but still build fails cmake --version cmake version 2.8.3

[tverbele]

Something went wrong during the build of ALE (I cannot see what from the screenshot). You can skip ALE in the build by adding -x :be.iminds.iot.dianne.rl.environment.ale:build to your gradle command.

[khalidpandit]

./gradlew -x build was successful but run.all stops at 87% Failed to start bundle be.iminds.iot.dianne.tensor-0.7.0.201803281542, exception Resolution failed [BundleRequirement {tensor.native}] ! Failed to start bundle be.iminds.iot.dianne.tensor.util-0.7.0.201803281542, exception Resolution failed [BundleRequirement{Import-Package be.iminds.iot.dianne.tensor;version="[0.7,1)"}] !

[tverbele]

./gradle -x build will skip the entire build and do nothing. ./gradle build -x :be.iminds.iot.dianne.rl.environment.ale:build will build everything except the failing ALE bundle. It is the latter that you need.

[khalidpandit]

[khalidpandit]

./gradlew build -x :be.iminds.iot.dianne.rl.environment.ale:buildNative i used this command still getting error

[tverbele]

This is again the error from before where JAVA_HOME is configured incorrectly. export JAVA_HOME=/usr/lib/jvm/java-8-oracle jni.hshould be residing in /usr/lib/jvm/java-8-oracle/include/

[khalidpandit]

I have my java path set in bashrc and /etc/environment as well.

What shall be the path?

I face following error

Khalid, are you running on the same machine? Now you are reporting stack traces on

khalid@khalid-HP-ZBook-15:~/dianne$

whereas above your screenshots indicate

khalid@khalid:

This makes it very difficult to spot your problems and help you. In short:

1. Make sure you have all build dependencies installed
2. Make sure you have JAVA_HOME pointing to your Java JDK installation dir, meaning that in this directory you can find include/jni.h
3. Skip ALE from the build as this requires additional dependencies, so use the following build command ./gradle build -x :be.iminds.iot.dianne.rl.environment.ale:build

Also, why do you need to build from source? You can perfectly run Dianne using the prebuilt binaries as done in the examples repo: https://github.ugent.be/e-p/dianne-examples

[khalidpandit]

i was trying on khalid@khalid: first but now i stuck to khalid@khalid-HP-ZBook-15:~/dianne$..

i corrected the JAVA PATH to point to the directory where include /jni,h

now build process shows this error

[khalidpandit]

while building lb command shows the no of bundles have increased to 44

[khalidpandit]

http://localhost:8080/dianne/ui/builder/builder.html in browser shows the UI

[khalidpandit]

the layer tab does not seem to be working

it fails to deploy those modules (LAYER)

[eliasdc]

It looks like we are getting there. First the fact that your build is still failing is because you do ./gradle build -x :be.iminds.iot.dianne.rl.environment.ale:buildNative instead of ./gradle build -x :be.iminds.iot.dianne.rl.environment.ale:build which will only skip the native build and not the complete ale project.

When running the project with ./gradlew the percentage never exceeds 90% as we run a frontend process which can be killed.

With the last screenshot I suspect you forgot to configure the modules. In the build tab double click each module to set appropriate values (not every module has configuration options but most do). This is still a bit hidden and should be improved before releasing a release candidate.
