应用错误收集

当我遇到一个有趣的错误时，我最近开始将一个大型Ant项目转换为一个Maven多模块项目。我一直遇到的问题是，我无法从另一个工件访问我的嵌套类，即使它们位于同一个包中（例如com.mypackage）。

对于这个项目，我们将我们的SQL查询存储在Groovy类中（多行字符串非常棒）并在我们编译的Java代码中引用它们。像这样：

ShipmentPackingQueries.groovy - 所有groovy文件都在src / main / groovy下


    package com.mypackage;

    class ShipmentPackingQueries {
        static class Queries {
            public static class Cartons {
                @Language("MySQL")
                static final String query1 = ''' query '''
            }

            static class CartonItems {
                @Language("MySQL")
                static final String query2 = ''' query '''
            }

            // and so on....
        }
    }

此文件被编译到稍后使用的jar中：mylibrary-core.jar。这些是我的maven-compiler-plugin设置 - JDK版本在标签中自动检测到，并且在我的机器上是openjdk 1.8：

                                <artifactId>groovy-eclipse-compiler</artifactId>
                                <version>2.9.1-01</version>
                            </dependency>
                            <!-- for 2.8.0-01 and later you must have an explicit dependency on groovy-eclipse-batch -->
                            <dependency>
                                <groupId>org.codehaus.groovy</groupId>
                                <artifactId>groovy-eclipse-batch</artifactId>
                                <version>2.3.7-01</version>
                            </dependency>
                        </dependencies>
                    </plugin>
            </plugins>
        </pluginManagement>
    </build>

    <!-- Set explicitly in the pom files for mylibrary-core and rest-core -->
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

当我观察工件mylibrary-core的编译时输出时，我可以看到正在成功创建类。


    [writing    com/mypackage/ShipmentPackingQueries$Queries$Shipments.class - #856]
    [writing    com/mypackage/ShipmentPackingQueries$Queries$CartonTypes.class - #857]
    [writing    com/mypackage/ShipmentPackingQueries$Queries$CartonItems.class - #858]
    [writing    com/mypackage/ShipmentPackingQueries$Queries$Cartons.class - #859]
    [writing    com/mypackage/ShipmentPackingQueries$Queries.class - #860]
    [writing    com/mypackage/ShipmentPackingQueries$Queries$Feed.class - #861]

我确认这些类文件也会进入工件jar文件。问题是当我尝试使用来自另一个工件的查询时：rest-core。我已经设置了rest-core来依赖于工件mylibrary-core。这是rest-core的示例文件：

ShipmentPackingResource.java - 所有java文件都在src / main / java下


    package com.mypackage;
    import static com.mypackage.ShipmentPackingQueries.Queries;

    public class ShipmentPackingResource {
        public void get() {
            Database.executeQuery(Queries.Cartons.getQuery1());
        }
    }

工件rest-core无法编译并显示消息“Cartons无法解析或不是字段”。我只看到在查看输出时出现两次ShipmentPackingQueries：


    [reading    com/mypackage/ShipmentPackingQueries.class]
    [reading    com/mypackage/ShipmentPackingQueries$Queries.class]

关于为什么maven-compiler-plugin没有读取与ShipmentPackingQueries一起使用的其他类文件的任何想法？我知道如果我将类从rest-core移动到mylibrary-core，我可以使它工作，但我想尽可能保持我的模块中的代码。谢谢！
