javax.activation似乎在Java 11 Open JDK中固有地存在，因此，如果您遇到此错误，请在您的pom.xml或build.gradle.gradle

maven <

<dependency>
    <groupId>com.sun.activation</groupId>
    <artifactId>javax.activation</artifactId>
    <version>1.2.0</version>
</dependency>

strong gradle

compile 'com.sun.activation:javax.activation:1.2.0'
