通过命令行运行 Swing Maven jar 应用程序不会构建数据库，但从 NetBeans 运行相同的应用程序时会构建数据库，如何修复？

问题描述 投票：0回答：1

我使用 Apache derby 嵌入模式编写了一个 Maven Java swing 应用程序。

使用 

flyway-database-derby
迁移数据库（创建数据库）。
使用 
maven-shade-plugin
来“清理并构建”具有依赖项的 jar。
使用过 Apache NetBeans IDE 21

案例 A：从命令行运行应用程序

如果我使用命令行启动 jar 文件

java -jar warehouse-box-1.0-SNAPSHOT.jar
，它会输出以下消息：

C:\Users\Saleh\Documents\NetBeansProjects\warehouse-box\target>java -jar warehouse-box-1.0-SNAPSHOT.jar
[AWT-EventQueue-0] INFO org.flywaydb.core.internal.resource.ResourceNameValidator - 1 SQL migrations were detected but not run because they did not follow the filename convention.
[AWT-EventQueue-0] INFO org.flywaydb.core.internal.resource.ResourceNameValidator - Set 'validateMigrationNaming' to true to fail fast and see a list of the invalid file names.

[AWT-EventQueue-0] WARN org.flywaydb.core.internal.database.base.Database - Flyway upgrade recommended: Derby 10.17 is newer than this version of Flyway and support has not been tested. The latest supported version of Derby is 10.15.

[AWT-EventQueue-0] INFO org.flywaydb.core.internal.command.DbMigrate - Schema "ROOT" is up to date. No migration necessary.
  • GUI 启动。
  • 数据库目录已创建。
  • 但是，表并未创建。如果我通过命令行连接到 Apache derby；它不输出任何表格（我的表格）。
ij> connect 'jdbc:derby:C:\Users\Saleh\warehouse-db;user=root;password=1212';
ij> show tables; # My tables were not listed, they were not created.

ij> select * from items;
ERROR 42X05: Table/View 'ITEMS' does not exist.

案例 B：从 NetBeans 运行应用程序：（没有问题）

如果我从 Apache NetBeans 中运行应用程序，则没有问题；应用程序启动并创建数据库，一切顺利。 NetBeans 输出：

cd C:\Users\Saleh\Documents\NetBeansProjects\warehouse-box; "JAVA_HOME=C:\\Program Files\\Java\\jdk-20" cmd /c "\"C:\\Program Files\\NetBeans-21\\netbeans\\java\\maven\\bin\\mvn.cmd\" -Dexec.vmArgs= \"-Dexec.args=${exec.vmArgs} -classpath %classpath ${exec.mainClass} ${exec.appArgs}\" -Dexec.appArgs= -Dexec.mainClass=warehousebox.root.MainRun \"-Dexec.executable=C:\\Program Files\\Java\\jdk-20\\bin\\java.exe\" \"-Dmaven.ext.class.path=C:\\Program Files\\NetBeans-21\\netbeans\\java\\maven-nblib\\netbeans-eventspy.jar\" --no-transfer-progress process-classes org.codehaus.mojo:exec-maven-plugin:3.1.0:exec"

颠倒案例A和B的顺序

如果我首先使用 NetBeans 运行应用程序（情况 B），然后再运行；关闭它并使用命令行运行应用程序（案例 A），现在应用程序使用命令行启动并且可以顺利工作而不会出现问题，并且它与之前在案例 B 中创建的数据库进行交互。 所以，案例 A仅当我首先通过从 NetBeans 运行应用程序来创建数据库时，才能正常工作。 相反后命令行的输出：

C:\Users\Saleh\Documents\NetBeansProjects\warehouse-box\target>java -jar warehouse-box-1.0-SNAPSHOT.jar
[AWT-EventQueue-0] INFO org.flywaydb.core.internal.resource.ResourceNameValidator - 1 SQL migrations were detected but not run because they did not follow the filename convention.

迁徙路线的迁移文件

地点及名称：

NetBeans 结构：

            └── db.migration/
                └── V1__warehouse_db_tables.sql

终于找到问题了。问题在于您创建遮光罐的方式。

您需要在 

org.apache.maven.plugins.shade.resource.ServicesResourceTransformer
中添加 
maven-shade-plugin
。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>3.6.0</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>warehousebox.root.MainRun</mainClass>
                    </transformer>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin>

为什么需要添加

ServicesResourceTransformer
？

提供某些接口实现的 JAR 文件通常随 META-INF/services/ 目录，将接口映射到它们的 用于服务定位器查找的实现类。搬迁 这些实现类的类名，并合并多个 将同一接口实现到一个服务条目中。

我本地的输出（成功）：
