I am new to XJC Maven plugin. I am trying to generate a Java class from XSD. I have placed the XSD file in the location src/main/resources/static/xsd (Say my filename is example.xsd). I have also created a package src/main/java/com/example/message where I expect the sources of my generated Java classes. My pom file looks like below:

But when I build the project, no files are generated in com.example.message. Can anyone please suggest what wrong I am doing?
If you do not specify destination folder your generated classes will be placed in /target/generated-sources/jaxb.
I would not place those classes in any folder or package under src/main/java: I think that generated files should be dropped and recreated every time you launch the build using Maven. In this way you are sure to have always the correctly generated file.
If you use IntelliJ you should be able to use classes, if you are an Eclipse user then you must add them to source folders (right click on folder -> Build Path -> Use as Source Folder).
You do not need to specify anything to include those classes when producing jar/war files, Maven will automatically include them.

I'm following a Udemy Course on learning SpringBoot, but I can't seem to get one of the dependencies installed. The tutorial asks to import a Tomcat dependency into pom.xml (in order to utilize JSP pages from resources), but after trying to import it:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId> <!-- Error comes from here -->
<scope>provided</scope>
</dependency>
I get the following error on the commented line.
Dependency 'org.apache.tomcat.embed:tomcat-embed-jasper:10.0.21' not found
What am I missing? I'm using IntelliJ, Java 18.0.1.1, and here is my pom.xml:

Can you remove the <repositories> section in pom.xml and try to build. Looks like the jar is not available in Spring repository. It will get downloaded from maven central if none mentioned.
I've been reading around on this site and others, trying to figure out how add these external jars without doing mvn install, and haven't had any success. I was reading somewhere that maven-shade could address my problem, but I could never get that to work? I know spring boot doesn't like system scope but it seems to error out if I choose something else?

You can create a new directory "lib" on your project, put your jars in this directory and then add them to your classpath.
If your IDE is IntelliJ you can follow this link:
Correct way to add external jars (lib/*.jar) to an IntelliJ IDEA project
If you use another IDE you have to find on google how to add jar on your project classpath.

i'm new to maven and geoserver as well. was just trying basic installation of geoserver and found the error in POM.XML file of maven project. Error is shown in two <dependency> tabs which are exactly 1st and 2nd after <dependencies> tab.
Errors :
Missing artifact org.geotools:gt-process:jar:8-SNAPSHOT
Missing artifact org.geoserver:main:jar:tests:8-ENTERPRISE-SNAPSHOT
Thanks for the solution in advance.
If you look at the quick start docs for geotools:
http://docs.geotools.org/latest/userguide/tutorial/quickstart/maven.html
step 7 "under Creating a new project"
If you are using a nightly build (such as 14-SNAPSHOT) and add a
reference to the snapshot repository.

I have taken a quick look at the versions available in this repository and to use it, you will need to change your maven co-ordinates to something like:
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-process</artifactId>
<version>10-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.geoserver</groupId>
<artifactId>main</artifactId>
<version>2.4.8</version>
<classifier>tests</classifier>
<scope>test</scope>
</dependency>
as the original versions you are after are not present.
I have a Spring Core Application which I would like to convert to a web project. I have already implemented all the business logic for my application in a normal Java Project using Eclipse IDE with Maven build.
But since I started out with a Core Java Project I do not have the WebContent folder or the Apache Tomcat wrapper. So what would be the best way to convert this project? Should I just change the pom.xml or does Spring have an alternative solution using the SpringBoot which I have already included in the pom.xml? (As you can tell I am new to Spring framework)
Here is my pom.xml

You can configure the directories required for Web under project facets. You can do that by,
Right click on the project properties. Select “Project Facets“, and
click “convert to faceted form…”
A nice tutorial here by mkyong have a look at it
I used the example gs-convert-jar-to-war provided by spring-io. It describes how to generate war packaging within a spring boot project.
The spring-boot documentation allows for using own parent poms, thus omitting the predefined parent pom for all spring-boot projects. The following dependency has to be added:
<dependencyManagement>
<dependencies>
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.0.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I applied this change (and only this change) to the example. Afterwards it is no longer possible to generate the war. I get following error message:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project gs-convert-jar-to-war: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]
Here is the complete listing of the modified pom.xml:

Is there any idea to overcome the problem?
In my project I will use my own parent pom, because it defines a lot of stuff regarding the company.
You removed the parent, so you lost its declaration of the WAR plugin configuration. Here it is:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
See here for the source code.
N.B. this is not necessary with Spring Boot 2.0 parent pom and above (the war plugin version is different), or if you use the latest war plugin.
