I having trouble getting Orika working using eclipse.... I added the maven orika dependencies (1.4.6) and I created a sample junit test 

import java.util.List;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import ma.glasnost.orika.MapperFacade;
import ma.glasnost.orika.MapperFactory;
import ma.glasnost.orika.impl.DefaultMapperFactory;

public class OrikaTest {

    @Test
    public void test() {
        //System.setProperty(OrikaSystemProperties.COMPILER_STRATEGY,EclipseJdtCompilerStrategy.class.getName());

        MapperFactory mapperFactory = new DefaultMapperFactory.Builder()
                .build();

        mapperFactory
            .classMap(PersonDTO.class, PersonEntity.class)
            .field("cellPhone", "phone")
            .byDefault()
            .register();

        PersonDTO dto = new PersonDTO();
        dto.setFirstName("John");
        dto.setLastName("Smith");
        //dto.setRoles(Lists.newArrayList("Role1", "Role2"));
        dto.setCellPhone("845-111-2222");

        MapperFacade mapper = mapperFactory.getMapperFacade();

        PersonEntity entity = mapper.map(dto, PersonEntity.class);

        assertEquals(entity.getFirstName(), "Jeff");
        assertNotNull("Roles not filled", entity);

    }

}

class PersonDTO {
    private String firstName;
    private String lastName;
    private String cellPhone;
    private List<String> roles;

    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public List<String> getRoles() {
        return roles;
    }
    public void setRoles(List<String> roles) {
        this.roles = roles;
    }
    public String getCellPhone() {
        return cellPhone;
    }
    public void setCellPhone(String cellPhone) {
        this.cellPhone = cellPhone;
    }
}

class PersonEntity {
    private String firstName;
    private String lastName;
    private String phone;
    private List<String> roles;

    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public List<String> getRoles() {
        return roles;
    }
    public void setRoles(List<String> roles) {
        this.roles = roles;
    }
}

When I run the unit test, I get the following exception:

ma.glasnost.orika.MappingException: ma.glasnost.orika.impl.generator.CompilerStrategy$SourceCodeGenerationException: class PersonDTO is not accessible at ma.glasnost.orika.impl.generator.MapperGenerator.build(MapperGenerator.java:105) at ma.glasnost.orika.impl.DefaultMapperFactory.buildMapper(DefaultMapperFactory.java:1372) at ma.glasnost.orika.impl.DefaultMapperFactory.build(DefaultMapperFactory.java:1199) at ma.glasnost.orika.impl.DefaultMapperFactory.getMapperFacade(DefaultMapperFactory.java:859) at OrikaTest.test(OrikaTest.java:37) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:271) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:70) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:238) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:63) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:236) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:53) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:229) at org.junit.runners.ParentRunner.run(ParentRunner.java:309) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192) Caused by: ma.glasnost.orika.impl.generator.CompilerStrategy$SourceCodeGenerationException: class PersonDTO is not accessible at ma.glasnost.orika.impl.generator.JavassistCompilerStrategy.assureTypeIsAccessible(JavassistCompilerStrategy.java:155) at ma.glasnost.orika.impl.generator.MapperGenerator.build(MapperGenerator.java:58) ... 27 more

Note: I see in the console eclipse printing the defined mapping. However, I get the above error when executing: 

MapperFacade mapper = mapperFactory.getMapperFacade();

If I attempt to use the EclipseJdtCompilerStrategy, by setting the system property, I get a different exception:

Any help would be greatly appreciated

关于

class PersonDTO is not accessible at
    ma.glasnost.orika.impl.generator.JavassistCompilerStrategy.assureTypeIsAccessible(JavassistCompilerStrategy.java:155)

您的PersonDTO类是包可见的，因此 Orika 代码无法从其包中访问它。让它成为一个public class问题应该消失。作为参考，请具体参见Orika 代码中的该行。

当您使用默认 (Javassist) 编译器时会发生这种情况。

对于 Eclipse 编译器，请仔细检查您是否添加了相关的 Maven 依赖项

<dependency>
   <groupId>ma.glasnost.orika</groupId>
   <artifactId>orika-eclipse-tools</artifactId>
   <version>1.4.6</version><!-- should correspond to your core Orika version -->
</dependency>

并在创建 mapperFactory 时启用编译器

MapperFactory factory = 
    new DefaultMapperFactory.Builder()
            .compilerStrategy(new EclipseJdtCompilerStrategy())
            .build();

系统属性应该用作后备，因此请使用上面的构建器方法。

有关详细信息，请参阅故障排除指南“启用步进调试”部分。
