Please excuse a newbie such as I for this silly question.
I am trying to install QueryDSL in my Java project in Eclipse Mars to use it for SQL querying. I do not use Maven yet, and don't know how to use it, though it's definitely on my to learn list.
The QueryDSL page points to their GitHub repository, but it's not clear to me how to add it to my project. Please advise on how can I get the full list of JAR files to add to my Eclipse Java project, without using Maven. Thanks!
Go to querydsl.com and click "Downloads" under "Documentation".

I'm having issues including bukkit/spigot/paper into my Eclipse since when I try "extends JavaPlugin" in my Class it does not seem able to import the file
I have tried versions of craftbukkit, spigot and paper on several occasions but it just does not seem to work:
From all the online tutorials I have seen, I have noticed that on their versions of eclipse the "Modulepath" and "Classpath" headings do not seem to be there, but for me they are right there:
Could someone please tell me how to fix this issue?
I'm using Intellij IDEA and there is a plugin that create all the file on it, if you really want a clean environment use this to create your project and go back on eclipse after, i can create it and send you the main folder if you can provide you paper version that you want
You cannot use paper as a External JAR. Instead download Bukkit or Spigot from the internet (or use BuildTools to compile your own jar file), and use those instead of paper.
I used the Spring Initializr website https://start.spring.io/ to create a spring boot program, and I wanted to delete the mvnw, mvnw.cmd, and .mvnw directory.
Is there any reason to keep these files maven wrapper files around?
I read What is the purpose of mvnw and mvnw.cmd files? and see that if I didn't have maven installed it would download maven and use that downloaded code to compile my java code.
If I delete them does that cause problems for someone else on the team?
I've always deleted them and it's never caused a problem that I'm aware of, but maybe it's because the team members all have maven installed
It seems like mvnw similar to the npx command in Javascript but only for the one mvn command.
Having Java and Maven installed seems (to me) to be a prerequisite to writing Java code, so I'm baffled as to what problem the Spring Team was solving when then decided to add this feature. If anyone knows the use case or reason that this was done, please share it.
Every couple of years I revisit this question and figured I'd ask it and have the answer in SO for future reference.
This is my first time trying to use external libraries and I'm having trouble getting it to work. I tried following this tutorial and got to this step and as a result I got an empty library. If anyone could point out what I'm doing wrong that would be great.
easy way to manage Your externals libraries in Maven or Gradle. Use one of this and all Your problems will gone.
I am an enthusiast attempting to play around and add things to an app that I have been using for the past year which the source codes are available in GitHub. Problem is when I clone or download the repository and open it in Eclipse, I get a ton of error codes whenever I try to 'run as' Java app (in particular I am unable to find the 'main class/starting point' there's way too many files to chose from to find it and most don't work) and when I try to extract the files to an executable jar it gives me a JAR exe that is unusable :-(. I know that the files are workable since I do use the executable jar that is available from the developer and others have also toyed around with the source codes.
Can anyone assist me with this? Maybe I am using the wrong Java manipulator/application. The program I am using for opening these files is Eclipse IDE for Java Developers and my operating system is 64bit Windows 10.
Also, here is the GitHub URL for the repository, in case anyone asks: https://github.com/DraqueT/PolyGlot.
I thank anyone who can be of some assistance as I have been working on this forever and can't seem to find a solution.
The github project looks a lot like a utility library than a full application. But the following could help:
Try to study the README file attached to the github project. (There is one in the source code according to the author). This would help you to setup the project.
Make sure to download all the dependencies for that project. Again, the author has provided some of them in the github project (I could see some Apache POI libraries in there somewhere), but getting the required jars on the maven repository isn't that difficult.
It would also help to know what type of project it is. For example, having a main method in a web application doesn't do much for you, but a Java SE project would need a main method to run. So try to find out what kind of project it is.
If all else fails, you could try to contact the owner of the repository or one of its contributors to assist you.
Cheers!
I am trying to convert one project to JPA enabled project by assigning "JPA Facet" from preferences > Project Facets in eclipse.
But, there is no option to select "JPA Facets".
After analysis, i found that i am even not able to create a new JPA project with eclipse, i am having.
I am using eclipse JUNO. I think, i am missing something in configuration.
I have tried installing eclipselink<>.jar to userlibrary configuration. But, it is not working.
Reason which i found is also mentioned in below duplicate question.
Cannot create JPA Facet: “project facet jpt.jpa could not be found”
In this also, it is mentioned that update to new eclipse. But, is there any way to find out, what is messed up in existing eclipse.
Here is what I did and it worked:
Go to help -> install new software
In work with select Neon - http://download.eclipse.org/releases/neon
(in my case)
In here you find "Web, XML, Java EE and OSGi Enterprise Development".
Open it!
Just installed everything that included the title "JPA"
Click finish, install, restart Eclipse
Now try again to find your facet!
