Expected behavior

As a CobiGen CLI user, I want CobiGen to be able to generate from non-build Java sources.

Actual behavior

The CobiGen CLI is not able to generate all the Java files from non-build Java source files. After building the Java project the generation is working.

Steps to reproduce

  1. Install devonfw-ide and CobiGen CLI
  2. Create a devon4j Java project (devon java create com.example.application.cobigenexample)
  3. Create a package and an entity class
    package com.example.application.cobigenexample.customermanagement.dataaccess.api
package com.example.application.cobigenexample.customermanagement.dataaccess.api;

import java.sql.Timestamp;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name = "Customer")
public class CustomerEntity {

  private String firstname;

  private String lastname;

  private int age;

  /**
   * @return the firstname
   */
  public String getFirstname() {
    return firstname;
  }

  /**
   * @param firstname the firstname to set
   */
  public void setFirstname(String firstname) {
    this.firstname = firstname;
  }

  /**
   * @return the lastname
   */
  public String getLastname() {
    return lastname;
  }

  /**
   * @param lastname the lastname to set
   */
  public void setLastname(String lastname) {
    this.lastname = lastname;
  }

  /**
   * @return the age
   */
  public int getAge() {
    return age;
  }

  /**
   * @param age the age to set
   */
  public void setAge(int age) {
    this.age = age;
  }

}
  1. Run Cobigen:
    devon cobigen generate core/src/main/java/com/example/application/cobigenexample/customermanagement/dataaccess/api/CustomerEntity.java
    Select 1,3,5,6,8 as increments

The following error occurs:

[INFO ] Failed

After building the project (devon mvn clean install -Dmaven.test.skip=true) this error does not happen

  1. Then after successfull generation add an attribute to the entity class
private String company;
public String getCompany() {
    return company;
}
  
public void setCompany(String company) {
  this.company = company;
}
  1. Run CobiGen again and select 5 or 8 as increments
    The following error occurs:

The error seems to be that a ClassLoader is unable to load a non compiled class. What I have tried (without success) is to compile the EntityClass with the JavaCompiler, however the ClassLoader was still unable to find and load the class.
