Maven cannot resolve AWS-CDK dependencies (Java)

I'm attempting to build a Maven multi-module project which uses the AWS CDK software.amazon.awscdk package.
However, I consistently get a DependencyResolutionException error:
[ERROR] Failed to execute goal on project github-api-infrastructure: Could not resolve dependencies for project pixee:github-api-infrastructure:jar:dev: Failed to collect dependencies at software.amazon.awscdk:aws-cdk-lib:jar:2.17.0 -> software.constructs:constructs:jar:[10.0.0,11.0.0): No versions available for software.constructs:constructs:jar:[10.0.0,11.0.0) within specified range -> [Help 1]
The error says it cannot find a software.constructs package with the right version, but it should exist on the Maven repositories.
I've tried updating my Maven version, clearing the Maven cache and rebuilding, but I get the same error.
This is the only module that fails to build, so I don't expect it to be a problem listed in DependencyResolutionException documentation such as the connection to the remote repository being misconfigured or a network problem.
The build works on my teammates computers, but not on mine. I'm not sure what could possibly be the issue, since we're on the same-ish Java (I'm on 17, they have 18) version and same Maven version.
Not familiar with the Java ecosystem, please let me know if additional clarification is needed.

Maven version:
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /opt/maven
Java version: 17.0.4, vendor: Private Build, runtime: /usr/lib/jvm/java-17-openjdk-amd64
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.4.72-microsoft-standard-wsl2", arch: "amd64", family: "unix"
Java Version:
openjdk 17.0.4 2022-07-19
OpenJDK Runtime Environment (build 17.0.4+8-Ubuntu-120.04)
OpenJDK 64-Bit Server VM (build 17.0.4+8-Ubuntu-120.04, mixed mode, sharing)
I'm running Ubuntu 20.04.5 LTS on WSL 2.
Update:
I tried rebuilding it yesterday and the build was successful with no errors. I didn't change anything. Perhaps the package repositories were updated?
I tried rebuilding it today and I get the same error as before. I wonder if it's an error due to how Maven is configured locally on WSL. But why would it affect just this package?
I'm thinking now the dependency resolution fails because of something on JFrogs side.

Finally the problem was with my permissions on JFrog. I was upgraded to an admin and I didn't encounter the same error during build again.

Maven IntelliJ Error Importing Class in Same Package

I'm working on a project using DeepLearning4J, Maven, and IntelliJ. I added a user interface class to my package. However, whenever I try to import a class from the same package into my UserInterface.java class, I receive the following error:
Information:java: Errors occurred while compiling module 'stock-analyzer'
Information:javac 1.8.0_121 was used to compile java sources
Information:3/9/17, 8:16 PM - Compilation completed with 2 errors and 0 warnings in 2s 143ms
/Users/raulie/CAP5600/stock-analyzer/src/main/java/UserInterface.java
Error:(5, 17) java: package main.java does not exist
Error:(9, 13) java: cannot find symbol
symbol: class StockAnalyzerBasicForUI
location: class UserInterface
I believe this is a dependency issue with maven, but have been unable to resolve. I tried "mvn compile" and "mvn clean install" in the project directory (where the pom.xml file is), but receive a similar error like the one shown above.
Below is the pom.xml file:

Any insight you can provide into what I'm doing wrong would be greatly appreciated. Thanks!

This looks like you created your intellij project wrong. Maven projects are created with src/main/java as the main source folder.
The fact it says main.java is telling me the way you setup the project it doesn't seem to recognize the source folder properly.

Vaadin maven compile themes

If I try to run in eclipse maven vaadin:compile-theme I get:
[WARNING] Vaadin plugin could not find any themes.
[INFO] No themes found. Use the parameter "vaadin.theme" to explicitly select a theme.
I have some themes in my project, how can i specify them?
I'm not sure how to do it correcty, can somebody help me?

killAfter deprecated warning when running exec:java

I have noticed that I get this warning every time I run my exec:java command in MAVEN.
[WARNING] Warning: killAfter is now deprecated. Do you need it ? Please comment on MEXEC-6.
How can I get rid of it? I have been searching for it, but no clue.

edit This answer is not valid anymore for newer versions (> 1.3.2) of the exec-maven-plugin.
For the down-voters please have a look at the timeline.
Jul 2014 - release of plugin version 1.3.2
Nov 2014 - posting this answer
Mar 2015 - release of plugin version 1.4.0

Update to version 1.4.0 of the exec-maven-plugin. The warning no longer appears.

choose one:
1) change exec-maven-plugin configuration in your pom by adding:
<killAfter>-1</killAfter>
2) or add command-line parameter:
-Dexec.killAfter=-1

java.lang.NoClassDefFoundError on running project with Java, but works when running with mvn exec:exec

I'm compiling and running some source code I got from a project called Structr (https://github.com/structr/structr). I'm able to run the program correctly with a maven mvn command but not using the JVM java command.
The compilation step goes well with maven clean install -DskipTests
On running the front-end (in the structr-ui directory), it goes well if using maven exec:exec but fails on java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui. I have some stack trace indicating java.lang.NoClassDefFoundError on org.structr.core.entity.AbstractNode and org.structr.core.EntityContext. What I find strange about this is that the maven pom.xml file in the exec entry we have
<plugin>
<groupId>org.codehaus.mojo</groupId>

The mvn exec:exec statement looks equivalent to the java JVM statement. This question may be basically; What is maven doing differently than java, that in the maven case making the program run correctly?
Edit - additional maven and java debugging information
On mvn -X exec:exec, The output is given here http://roberthoff.com/files/mvn_exec_trace.txt
And on java -server -Dfile.encoding=utf-8 -XX:+UseNUMA -Xms1g -Xmx1g -classpath target/lib/*
;target/structr-ui-0.8.2.jar org.structr.Ui we have http://roberthoff.com/files/java_trace.txt

You have a valid question here, because according to the Maven documentation on the exec:exec goal you would need to have the <\classpath> stanza in your configuration in order to include the entire project module classpath.
However, it appears as though Maven is running the program with the fully (and properly) configured classpath for some reason.
In order to get to the bottom of the problem, I'd run Maven with the -X command line argument and carefully scan through the debug output until I found the exact command it runs. Then I'd try running it from the same directory, ensuring I am using the same Java installation and see if it works.

Notice the maven-dependency-plugin in the pom. It copies all dependencies during the package phase to target/lib folder and then they are on classpath. Following should work:
maven clean package -DskipTests
java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui
