I am using IntelliJ Idea 14.1.4 and Gradle, and I am trying to create sub projects and nested sub projects:
Project
|--Research
|--Development
|--Algorithms
The reason for this is that research algorithms are separate from the development implementation. They are written in different languages (Python vs. Java) and used by different programmers, however I still want to maintain one Gradle project, so eventually researchers would be able to use stable existing algorithms implementations when developing new ones.
My problem is that Idea doesn't recognize properly the Gradle structure of the second level Gradle sub project: Project is recognized well, Research and Development are recognized well, but the Algorithms sub project is not recognized:
The code inspection of the gradle.build file in Algorithms project is highlighted as a warning with a message that test cannot be applies to Groovy.lang.closure Note that below is the complete build.gradle:
test{
useTestNG()
testLogging.showStandardStreams = true
}
Also, when I try in Idea Run->Edit Configurations->Defaults->Gradle and trying to choose Gradle project, I see that in the pop-up menu Development and Research do appear as sub-projects of Project, but Algorithms appears as a stand alone project.
Making the project however does create all the binaries and manually running a test case also works well.
When I run Gradle for command line, it appears to be working well and recognizing all nested projects: All the code is being compiled and tests are being ran. So the question here is if there is an Idea issue here which is not working correctly with Gradle, or am I doing something wrong?
Code for build.gradle inside Project:
allprojects {
group 'com.project'
version 'v0.1'
repositories {
mavenCentral()
}
}
Code for settings.gradle inside Project
rootProject.name = 'Project'
include 'Development'
include 'Development:Algorithms'
include 'Research'
Code for build.gradle of Development sub-project:
subprojects {
apply plugin: 'java'
repositories {
jcenter()
}
dependencies{
testCompile 'org.testng:testng:6.9.4'
}
}
Other code samples that I might be writing wrong (most of them are auto generated by Idea:

In Algorithms.iml the original (auto generated) value of external.root.project.path was $MODULE_DIR$/... I have tried setting it to $MODULE_DIR$/../.. to see if it will change anything. After each change I have ran rebuild.
****************************Edit********************************
Further investigation shows an issue with the workspace.xml file:
There is a GradleLocalSettingsElement there that was automatically created, but appears to be wrong: There are two different entries: one for Development and Devlopment:Algorithms and onw for the rest, so I might have did something wrong when I created the project.
My question is if there is a reference for the structure of this file and specifically for the elements inserted by the Gradle plugin?

Computer vision involves analyzing patterns in visual images and reconstructing the real-world objects that produced them. The process is often broken up into two phases: feature detection and pattern recognition. Feature detection involves selecting important features of the image; pattern recognition involves discovering patterns in the features. We will investigate a particularly clean pattern recognition problem involving points and line segments. This kind of pattern recognition arises in many other applications such as statistical data analysis.

I need to parse this XML file and assign values to its corresponding class objects.Which is the best option to parse such an xml file.
JAXB sounds good to me but the POJOs were already written by someone and now i will have to rewrite and deploy them.ALso teh xml file has some errors while running xjc command.
DOM approach seems to be very cumbersome n error prone.
Please suggest.
PS:Kindly excuse my beginner level knowledge.
the JDK project comes with SAX(Simple API for XML) accessible by importing org.xml.sax.*.
You may take a look at this https://www.tutorialspoint.com/java_xml/java_sax_parse_document.htm for an introduction to the subject.
My project is started to be large, so I decided to split it into separated modules - gui and domain. My domain module mustn't know that it is a part of Android project, so I created java-library module and put some classes there. It works like a charm but there is a problem when I add some other dependencies inside my java-library module like RxJava. I've created a Main class to simply test my code. Builds passes, but when it tries to invoke RxJava classes it crashes with exception:
Exception in thread "main" java.lang.NoClassDefFoundError: io/reactivex/Observable
at com.example.domain.Main.main(Main.java:13)
Caused by: java.lang.ClassNotFoundException: io.reactivex.Observable
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
... 1 more
My Main class:
package com.example.domain;
import io.reactivex.Observable;
public class Main {
public static void main(String[] args) {
Observable.just(1)
.subscribe(integer -> System.out.println(integer));
}
}
My build.gradle file:
apply plugin: 'java-library'
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
api 'io.reactivex.rxjava2:rxjava:2.1.2'
}
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
1) If I use com.android.library instead it works
2) If I add RxJava library as a .jar file it changes nothing
EDIT:
I looked into Domain.iml file and I found something strange:

<orderEntry type="library" exported="" name="reactive-streams-1.0.0" level="project" />

Unfortunately if I sync my build.gradle file it overrides my modification.
How to make it works permanently and why this acts like this?

Have you tried to change the scope via Android Studios Project Structure?
File -> Project Structure then select the Dependencies Tab and add the Dependency for the required module. In your case that would be java-library I believe.
As far as i know you can't change the scope of the dependency once added. So if you have already added it, try to remove and add it again. Be sure to assign the implementation scope though and see if it works.
I hope this was helpful
We have a project being managed by more than 20 developers and most of them use intellij.
I was wondering if we can source an xml file somehow so that every developer doesn't have to import code style settings manually.
How to properly import Java code style settings with IntelliJ?
This thread suggests that we have to manually import the xml file and only then we will see those settings will come into effect. Is there a setting that can import the code styles automatically?

The above settings in .idea/codestyleSettings.xml did the trick.
I'm at my wit's end with this.
I have a VERY simple installation descriptor for izpack for a two-package Java app on Windows. Everything works as intended EXCEPT for the shortcut creation. The shortcut panel doesn't seem right, for a start. The label "ShortcutPanel.regular.startup" is displayed instead of "run at startup" or anything of the sort in the startup execution checkbox.
After running the installer, the shortcuts simply aren't created. Here's what my install.xml looks like, it's pretty straightforward:
<izpack:installation version="5.0"

Then there's the shortcutSpec.xml. My pom moves it to my staging directory:

target="java -jar $INSTALL_PATH/pack2subdir/pack1.jar"
workingDirectory="$INSTALL_PATH/pack2subdir/">
<createForPack name="pack2" />
</shortcut>
The installer simply doesn't create any shortcuts anywhere. It finishes with no error messages no logs no stack traces no nothing.
Help.
I fixed that by going into the izPack/lib/izpack-core-5.0.9.jar and opening the /com/izforge/izpack/bin/langpacks/installer/ folder in it. Then editing the bra.xml file and adding the following line:
<str id="ShortcutPanel.regular.startup" txt="Iniciar com o Windows"/>
Then save and update the file in the jar and rebuild your instalation.
