How to convert maven project to gradle?

I have a project (spring + angular) built on maven. And I would like to replace the automation tool using gradle.
The project contains 3 pom.xml files. The structure looks like this.
-MainApp
-pom.xml
-- spring (contains pom.xml)
-- angular (contains pom.xml)
In summary, the application's root folder contains a pom.xml file, and it also contains 2 folders angular and spring, which have a pom.xml file in their projects.
And I don't know much about how to do it, because some pom.xml files contain a reference to other pom.xml files. How can I carry out this process?
Below I paste the pom.xml files

According to this documentation, gradle init command will convert the maven pom files into gradle. As you have child pom.xml files also, I suggest to start going to the child directories first and run this command.
First spring project directory, next angular project directory and last main project directory.

Failed to execute goal org.codehaus.mojo:jaxws-maven-plugin:2.4.1:wsimport

I am getting an error while I was generating code by jaxws wsimport plugin in my Java project.
I have tried every way in pom.xml file but I could not compile successfully. I got the error where is in the title.
I might give some details more about that I have tried until now.
Is there anyone encounter with this compilation error?

How to configure pom files and TeamCity to build dependent modules in maven java project?

I have project which consists from two modules. One of them considered to be main. So the second depends on first. Also I should generate javadoc jar files for modules. The output should be four .jar files: 2 module jar files and two javadoc jar files.
Locally, to generate both jar files I should repeat these step several times (I don't know why):
Build first one and install to local maven repository.
Then I can build second one.
Without installation of first modules I can't achieve packaging phase, because when I test second module it cannot find first module jar file.
Could I do all of these steps by one build process?

You just call mvn clean install on the parent project. It will build both modules in the right order.

I found solution. The error was received because mainmod module was accessible for secondmod module only for test scope <scope>test</scope>. Then I added new dependency with same artifactId, groupId and version, but assigned compile scope. Of course, it shows me warning about repeatition. However, it solves the problem.
Thanks for all!

AspectJ module dependency with Maven - How get working the Inter-type declarations methods of a dependency module

This is my situation:
I have a maven project my-project-aj-dependency composed by two jar modules:
my-project-aj-dependencyJarWithAJ (where I have an Inter-type declaration, see the ahah() method below inside the aspect AppWithAj_Ahah.aj)
my-project-aj-dependencyJarWithoutAJ
My problem is that I would like to use some declared method defined in the aspect of the first module inside the second module, but probably I missed something.
My poms configuration is the following:

Where AppWithAj.java is:
package org.my.project.aj.dependencyJarWithAJ;
public class AppWithAj {
public static void main( String[] args ){
System.out.println( "Hello World!" );
}
}
and AppWithAj_Ahah.aj is:
package org.my.project.aj.dependencyJarWithAJ;
public aspect AppWithAj_Ahah {
public String AppWithAj.ahah(){
return "Ahahahah!";
}
}
and finally App.java is:
package org.my.project.aj.dependencyJarWithoutAJ;
import org.my.project.aj.dependencyJarWithAJ.AppWithAj;
public class App {
public static void main( String[] args ) {
System.out.println( "Hello World! " + new AppWithAj().ahah());
}
}

Your solution is way too complicated:
The AspectJ (AJ) module needs the AJ Maven plugin and a dependency on aspectjrt. So far, so good.
But the declared aspect only affects a class within its own module, extending it via ITD. So there is no need to use the AJ compiler on the pure Java module which only calls a method from the AJ module. It is irrelevant that the called method was created by ITD, to the other module it looks just like normal Java.
Consequently, all the non-AJ module needs is a normal dependency on the AJ module because it uses one of its classes. The AJ runtime dependency is transitive and should be used automatically.

Please note: I have added the Exec Maven plugin just for demo purposes, so you can do something like this:
mvn clean install
mvn -pl my-project-aj-dependencyJarWithoutAJ exec:java
Then you should see something like this on the console:
(...)
[INFO] --- exec-maven-plugin:1.4.0:java (default-cli) # my-project-aj-dependencyJarWithoutAJ ---
Hello World! Ahahahah!
Remove Exec Maven from both the root and the plain Java POMs in order to get even shorter POMs.

I got it working with this pom configuration:

Here I show it working: AspectJ module dependency with Maven
Edit:
It seems that if the nonAj project doesn't have a AspectJ nature it warns you near the .aj defined methods (although it works fine if you simply launch it, for eclipse it is not an error, by the way this not allow you to use the autocomplete ad fills the code with wanings...). This is the snapshot:

Merge Java module dependencies resources into WAR using Maven

I have a multiplatform project which has several language-specific profiles. The HTML-platform-specific module depends on an "assets-core" module and if "en" profile is enabled, an "assets-en" module resources should also be included into WAR.
Assembling WAR works just fine with an exception that if "assets-core" module contains file with the same file name as "assets-en", it is not overwritten by the file from "assets-en" module.
I tried to use maven-resource-plugin:
<build>
<resources>
<resource>
<directory>${basedir}/assets-en/src/main/resources</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
</build>
with
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>copy-prod-resources</id>
<phase>process-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<overwrite>true</overwrite>
<outputDirectory>${basedir}/target/classes</outputDirectory>
<resources>
<resource>
<directory>${basedir}/assets-ar/src/main/resources</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
and <maven.resources.overwrite>true</maven.resources.overwrite> enabled as other threads suggests, but nothing worked.
maven-war-plugin overlays could also be the solution but I can't have resource module to be packaged with <type>war</type> because the same module is also included in Java project.
Here are the relevant parts of my pom.xmls:

OK, so I finally have found a solution. You need to get rid of dependencies to modules and copy the resources using maven-resources-plugin:
