我正在尝试使用此处描述的 jpa-ddl-maven-plugin，但使用 Apache Maven 3.0.3 时出现以下错误。有什么想法我哪里出错了吗？

我的 pom.xml：

<plugin>

                   <groupId>it.linksmt.tooling</groupId>

                   <artifactId>maven-jpa-ddl-plugin</artifactId>

                   <version>1.0.0-SNAPSHOT</version>

                   <extensions>true</extensions>

                   <configuration>

                           <targetDbPlatform>OraclePlatform</targetDbPlatform>

                           <persistenceUnitName>test-entity-api</persistenceUnitName>

                           <persistenceUnitFile>META-INF/persistence.xml</persistenceUnitFile>

                   </configuration>

            </plugin>

设置.xml：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <pluginGroups>
        <pluginGroup>it.linksmt.tooling</pluginGroup>
    </pluginGroups>
</settings>

您正在尝试使用插件的SNAPSHOT版本，它不会在 Maven 的默认存储库 - Maven Central 中找到。
查看插件谷歌代码页，目前似乎处于测试阶段，没有发布版本。
你有几个解决这个插件的选项：

  1. 按照此处所述从源代码构建它并将其安装到本地 Maven 存储库。这仅在您的机器上有用。
  2. 构建插件并将其部署到存储库管理器，例如Artifactory。这将帮助您与其他团队成员/CI 服务器共享插件。
  3. 从此存储库中解析插件。注意，我是通过谷歌搜索找到的，但不知道是谁在管理它。您必须为此定义一个新的存储库。
