I was following along with the Creating a Simple Hello World Backend API tutorial (GAE) and all was running fine via local terminal but as soon as I opened the project in IntelliJ, IntelliJ can't build the project...
The pom file has a bunch of errors about being unable to find any dependencies, however I can still build the application just fine outside of IntelliJ.
I'm not overly familiar with Maven but I believe it is configured correctly in the IDE as I can build other generic examples generated by IntelliJ. I've attempted to re-import all dependencies but no luck...
Is there something else I need to do here?
Snippet from the pom file where both dependencies are failing to find versions.

Your appengine.version property is recursively defined, so IntelliJ can't figure out what it is. Substitute <appengine.version>${appengine.version}</appengine.version> with <appengine.version>1.9.24</appengine.version> and you should be fine.

I am having a difficult time attaching Spring 5.3.x source code in eclipse.
I tried multiple ways one of them was to add a source to Java build path. However, I am not able to find the spring 5.3.x source code itself.
I have searched the official spring site - https://spring.io/blog/2018/10/30/spring-boot-2-1-0
on git too https://github.com/spring-projects
none of them has source code.
Another was to Right-click on the project -> maven -> Download Sources. It started updating the project however I still don't see the source code.
Can anyone help me solve this?
Your current java runtime in eclipse seems to be jdk8.
Go to Eclipse -> Preferences -> Java -> Installed JREs and switch to JDK11.
Then delete the project and reimport it again.
There might be some other issues in your project, after you switch to JDK11, but in this case I would need more information, including your pom.xml.
Also, check your project outside the eclipse, with command-line: "mvn clean install". Make sure that it compiles successfully, before importing it to eclipse. Make sure your JAVA_HOME points to JDK11
Here is the example of pom.xml for JDK11 Spring Boot 2.4.2 project. Compare it with your own pom.xml:

If nothing else helps, try to clean your local maven repository.
Deleting folder m2/repository/org/springframework should be enough
I have 2 Spring boot maven projects(module A, Module B). And they both are added as modules to a parent project. Both Modules have some common dependencies and java classes(Domain objects), so I created third module Module C, and placed all the common java files and dependencies there.
I added the Module C to parent pom as one of the module. And added Module C as dependency to Module A and Module B. In Module A, B wherever the classes of Module C is referred there it was resolved and is pointing to Module C Classes (on ctrl+click).No error was shown in eclipse and maven dependencies are updated. But when I build the projects either from Parent pom or build Module A alone (after building the module c), I get cannot find symbol error in the places where module C classes were referenced.
Below are my pom.xml's

Whats wrong with my configuration. Any help is much appreciated. Thanks.
If its a spring project the root folder of the jar would be BOOT-INF.
If you create a normal project jar it wouldn't be having BOOT-INF.
The way it works is if you have a Project A and it has dependency on x.jar
Say Project A needs com.x.y.ClassA.class from x.jar it will search in root folder of x.jar with this path x/y/ClassA.class.
In your case as it was a spring project the resolution didnt work and it was complaining about that.
I guess that the spring-boot-starter-parent is the culprit.
By using it as a parent POM to your parent POM, you are building all your modules with it. AFAIK, jars build with spring-boot-starter-parent cannot be used as dependencies because the classes are moved to a different directory inside the jar.
As I am not Spring expert, I cannot really offer you a good solution for this.
Hi I am new to Maven and JSoup and trying to run an example in Intellij so I can get an understanding of JSoup.
I added the dependencies of JSoup to my POM.xml file. I pushed to Github when the project was working. As soon as I pulled from Github the project won't run. So I went into the terminal and getting JSoup errors that certain imports don't exist. I tried to 'run' as a Maven project but now I'm even more confused.
Please see the image below which demonstrates the file structure. The code is simple its the config / setup that I am really struggling with.
Project Structure
The POM.xml content is seen below:

Hopefully someone can help with this.

We have a spring boot application which has its parent defined as spring-boot-starter-parent. But in our project, we have a parent pom with distribution management defined in it, and all the submodules in the project inherit from it. Now, since the spring boot application already inherits from spring-boot-starter-parent, and I do not want to duplicate the distribution management, I thought of having a custom spring boot starter module just to be able to define the distribution management in there and then include this custom spring boot starter as a dependency in the spring boot application. But when I do a mvn clean install deploy of the spring boot application it fails with the error shown below:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.
2:deploy (default-deploy) on project crs-acc-eve-gridgain-load-app: Deployment f
ailed: repository element was not specified in the POM inside distributionManage
ment element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help

Is it the right way to achieve this? or there any other recommended ways of doing it?
Given below are the poms of custom spring boot starter parent module:

There is no requirement that your build should be configured with the spring-boot-starter-parent. If you already have a parent with some distribution management, feel free to keep it. You'll need to adapt the parent a bit. Here are couple of options:
If the whole project is spring boot based, maybe your parent could inherit from the Spring Boot starter parent? This may not work if you have a parent that is used within the entire organization
You can keep your parent as it is and use the spring-boot-dependencies BOM instead. See the documentation for more details. You'll have to copy the bits of the parent that you use (such as the plugin definition) but it's not a ton of work.
Your proposal will never work. BOM only imports <dependencyManagement>. What you're looking for is mixin and it's not supported by Maven yet.
At my workplace, different groups works on providing different services.
My team consumes these services. Currently, whenever a new version of Service is rolled out, we manually change the pom.xml to the latest version of dependency and then make a build. I am wondering if there is an automatic way of pulling latest release into build.
Here is an example to explain:
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<groupId>com.company.product</groupId>
<artifactId>User-Application</artifactId>
<version>1.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<properties>
<Service1-version>1.0.2</Service-1>
<Service2-version>1.1.2</Service-2>
<Service3-version>2.0.2</Service-3>
</properties>
<dependencies>
<dependency>
<groupId>com.company.product</groupId>
<artifactId>Service1</artifactId>
<version>${Service1-version}</version>
</dependency>
<dependency>
<groupId>com.company.product</groupId>
<artifactId>Service2</artifactId>
<version>${Service2-version}</version>
</dependency>
<dependency>
<groupId>com.company.product</groupId>
<artifactId>Service3</artifactId>
<version>${Service3-version}</version>
</dependency>
.....
....
</project>
When new release of each service is made, we manually change the pom.xml to get the latest dependency. How can this be managed automatically?
The versions-maven-plugin should be able to do this with the task versions:update-properties. See an example here.
