How to resolve a required class was missing while executing : java/sql/SQLException

Question

我有一个旧项目，每当我运行像

mvn clean install

或

mvn datanucleus:enchance

这样的命令时，我都会收到像Failed to execute goal org.datanucleus:maven-datanucleus-plugin:3.1.1:enhance (default) on project springboot -appengine-standard：目标org.datanucleus的执行默认值：maven-datanucleus-plugin：3.1.1：增强失败：执行org.datanucleus时缺少必需的类：maven-datanucleus-plugin：3.1.1：增强：java /sql/SQLException

我有以下 pom.xml 文件：

我有以下 datanucleus.properties 文件：

javax.jdo.option.ConnectionDriverName=org.apache.derby.jdbc.EmbeddedDriver
javax.jdo.option.ConnectionURL=jdbc:derby:eg;create=true 
javax.jdo.option.ConnectionUserName=root
javax.jdo.option.ConnectionPassword=root

datanucleus.autoCreateTables=true
datanucleus.autoCreateSchema=true
datanucleus.autoCreateColumns=true
datanucleus.autoCreateConstraints=true
datanucleus.RetainValues=true

我尝试将 maven-datanucleus-plugin 更新到不同的版本。但是，它没有用。 如何解决以上问题？
