Gradle編譯專案Druid找不到tools.jar和jconsole.jar

原因：jdk11之後不支援druid的兩個依賴

方法一：

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid</artifactId>
  <version>1.2.5</version>




方法二：

<!--      <exclusions>
        <exclusion>
          <groupId>com.alibaba</groupId>
          <artifactId>tools</artifactId>
        </exclusion>
        <exclusion>
          <groupId>com.alibaba</groupId>
          <artifactId>jconsole</artifactId>
        </exclusion>
      </exclusions>-->
