It is said that Intellij idea would automatically download resource code from maven for maven projects. However I am still having "decompiled .class file bytecode version 50.0". I would like to view the resource code from .java.
right click on the project. maven -> download resources and documents (or just download resources). I have already checked the settings -> maven ->importing ->sources and documents, but this does not work no idea why.

I am trying to make use of modules and gradle subprojects and either receive compile time errors or complaints from IntelliJ.
My project structure is as follows:
Root
- settings.gradle
- core
- build.gradle
- desktop
- build.gradle
- src/main/java/module-info.java
The desktop build.gradle file as a requirement on core as:
dependencies {
implementation project(":core")
}
There is no reference to the "core" project in the module-info.java files.
In this configuration, IntelliJ doesn't like usage of classes from the "core" project in the "desktop" project (I see a lot of red), but running gradlew.bat desktop:run works with no issues. Bug with IntelliJ? I am using microsoft's openjdk, but hopefully that doesn't matter.
My best attempt to fix this, was to add a module-info.java file to the core project as well and reference the core project in the desktop project's module-info.java file. Unfortunately this configuration, while making IntelliJ happy, renders me unable to run the desktop from command line anymore. I get errors about the core project being unable to find required modules that are the exact same as the required modules I pull in for the desktop module. I think this might be an error on my part, but I'm not sure how or what to do to fix it.
Would appreciate any insight.
P.S. Of these issues, I think I would prefer to get IntelliJ working with the first setup, because I intend to have this core library be shared between the desktop project and an android project, and while I haven't looked into it yet, I am not sure Android supports new java modules?
I think terminal should be the first priority. If your original setup made it compiled successfully under terminal, then there is no problem in your project. Do not add extra files for just making the IDE happy.
There's still something you can do. The first step is compiling your project successfully under terminal. This step downloads all the necessary dependencies before IntelliJ, reducing the problem scope to IntelliJ's linking and indexing. Then there are some options:
In the Gradle tool window, click the top-left button Refresh all Gradle projects.
Delete all the .idea folders in your project. Then open the root folder of your project via UI or CLI.
Click the invalidate caches/restart in the main menu.
You can also also create a new Gradle multi-module project with command gradle init, and open it with IntelliJ. It should be analyzed by IntelliJ normally. Then you can compare its project structure with yours. Maybe there's something different.
Hope these steps could help you.
I've created a new project in IntelliJ.
When I go in to:
Project Structure -> Libraries -> Add -> From Maven -> 'com.atlassian.seraph:atlassian-seraph:3.0.3'
I get the error message 'No files were downloaded for com.atlassian.seraph:atlassian-seraph:3.0.3'
Backstory:
I'm using IntelliJ to write a custom SSO authenticator for JIRA. This is not a JIRA plugin, it's just a class that a custom JSP will use.
I intend to produce a JAR and put it in WEB-INF/lib.
I'm not sure what I've missed here. This is my first exposure to maven and I've googled this extensively.
If you did not change the default remote repository of your maven, it should be this . It seems that the artifact (com.atlassian.seraph:atlassian-seraph:3.0.3), you are looking for, is not in the default remote repository. There are two solutions for your case,
1.Add a new remote repository, which has this artifact, to your project.
2.Find the jar file somewhere on internet, add it to your project as an external jar file. Here is a great tutorial about this.
I've changed from idea 14 to idea 15, and downloading maven jar feature started to work)
My Maven setup in ide aimed to external v3.2.1, but may be it would work even with bundled one.
Currently have a hard times working on one project. While building with maven I'm getting success but when I open the project all classes are red with unresolved dependencies and folder "External Libraries" contains only JDK classes.
Does anyone know what might be the reason of this?
Thanks in advance.
I'm using Intellij Idea 14.0.2 and Maven version 3.2.5
Enable auto reload for your pom file(s). intelliji doesn't do it automatcally unless you enable it.
To do so, just open a pom file and you'll see a popup that asks you if you to enable auto relaod.
I am new to IntelliJ but coming from Eclipse I expected Maven support to be far better. It really is but I could not find how to define a remote archetype catalog in IntelliJ (14.1).
All I could find was a way to add a Archetype manually but that is not what I need. I would like to point to a XML file on a remote server that contains the list of all archetypes available.
In Eclipse, it looks like this :
Maybe you would like to try an Intellij Plugin that I wrote yesterday. It enables you to add remote archetype catalogs to Idea: Maven Archetype Catalog plugin
To make my answer more clear: I had the same issue that it struggles me that you can add Maven Archetype Catalog files in Eclipse, but not in IntelliJ IDEA. So I tried to write a plugin for IntelliJ IDEA, so that you can actually define URLs to archetype-catalog.xml.
The plugin just parses those URLs and provides the Maven Archetypes to the list of available Archetypes in IntelliJ IDEA.
After installing the Plugin you can find a new entry in the Settings menu at File - Settings - Build, Execution and Deployment - Build tools.
I know this is kinda old thread, but in the future if some one will look for it.
This Maven Archetype Catalogs is a plugin for intellij that allows import external archetypes from a URL.
It solved my problem on Linux, haven't tried it on Windows.
To add this plugin go to File->Settings->Plugins->Browse repositories
in the search bar type "Maven Archetype Catalogs". Install and restart.
To use it go to File -> Settings -> Build, Execution, Deployment -> Build Tools -> Maven Archetype Catalogs. click the '+' and add the archetype-catalog
It seems that there is a plugin to do this - Maven Archetypes. The reviews are not favourable, and I have never used it though so cannot comment to its effectiveness.
You could also (assuming Windows/IntelliJ 14), edit C:\Users\<username>\.IntelliJIdea14\system\Maven\Indices\UserArchetypes.xml and add the archetypes manually. Not ideal, but still workable.
Screenshots are made in IDEA 14, I've also checked IDEA 13, it's also true for it.
If this is what you need
Then it's in the Preferences:
just a simple question: I need to add a Maven dependency to a Eclipse Plugin project.
The project has not a POM file, so I converted it to a Maven one.
Now I have plugin.xml file and pom.xml file. POM contains the dependency I need to satisfy, but it's ignored; I mean, I can't resolve an import in source code referring to that import.
Can you help me?

I read about Tycho plugin, but online configurations don't work.
If I'm reading this correctly, you've just started by adding a Maven dependency to your project, but don't have the dependency available for Eclipse to validate your code against.
You will need to start a Maven build after you add a brand new dependency so that Maven can add that to your local cached repository. Once the Maven build is done, Eclipse should recognize your imports properly.
You may want to check whether the dependency you are looking for is available in the Eclipse Orbit.
The Orbit project is basically a repository of libraries to make them available for Eclipse Plug-in Development. What is especially nice in the Orbit libraries is that they also provide the sources. Thus, it is possible to view the implementation and get proper JavaDoc and so on.
Example
One can find the com.google.gson library using the update site
https://download.eclipse.org/tools/orbit/downloads/drops/R20190602212107/repository
Thereby, the part R20190602212107 refers to the Orbit build name that you find on the downloads page of the project.
