我跟踪了这个URL，下面的设置真的帮助了我。我在Macbook Pro中使用带有STS IDE的Java 10。这招很管用。

   <dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>javax.activation-api</artifactId>
    <version>1.2.0</version>
</dependency>

这个问题的根本原因是使用JDK11的Gradle守护进程，要么你把你的JAVA_HOME设置为JDK11，要么你在使用JDK11运行的共享守护进程中运行Gradle任务。

为Android:

检查您的项目结构设置，您可以从那里将JDK更改为JDK8。 您还可以设置JAVA_HOME和指向java8的home。

不是答案，而是一个附录:我得到的原因是，如果JAVA_HOME指向Java 9安装(准确地说是Java版本“9.0.1”)，则运行groovysh (Groovy 2.4.13)会失败:

解决方案是:

Go to the JAXB Project at github.io ("JAXB is licensed under a dual license - CDDL 1.1 and GPL 2.0 with Class-path Exception") Download jaxb-ri-2.3.0.zip Unzip wherever you put your java infrastructure files (in my case, /usr/local/java/jaxb-ri/). Other solution may exist (maybe via SDKMAN, I dunno) Make sure the jars in the lib subdirectory are on the CLASSPATH. I do it via a script started on bash startup, called /etc/profile.d/java.sh, where I added (among many other lines) the following loop:

打包到函数中…

function extend_qzminynshg {
   local BASE="/usr/local/java"
   for LIB in jaxb-api.jar  jaxb-core.jar  jaxb-impl.jar  jaxb-jxc.jar  jaxb-xjc.jar; do
      local FQLIB="$BASE/jaxb-ri/lib/$LIB"
      if [[ -f $FQLIB ]]; then
         export CLASSPATH=$FQLIB:$CLASSPATH
      fi
    done
}

extend_qzminynshg; unset extend_qzminynshg

它确实有效!

这对我很管用。只添加jaxb-api是不够的。

        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>${jaxb-api.version}</version>
        </dependency>
        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-impl</artifactId>
            <version>${jaxb-api.version}</version>
        </dependency>
        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>${jaxb-api.version}</version>
        </dependency>

为了解决这个问题，我在我的项目中导入了一些JAR文件:

javax.activation-1.2.0.jar

http://search.maven.org/remotecontent?filepath=com/sun/activation/javax.activation/1.2.0/javax.activation-1.2.0.jar

jaxb-api-2.3.0.jar

http://search.maven.org/remotecontent?filepath=javax/xml/bind/jaxb-api/2.3.0/jaxb-api-2.3.0.jar

jaxb-core-2.3.0.jar

http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-core/2.3.0/jaxb-core-2.3.0.jar

jaxb-impl-2.3.0.jar

http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-impl/2.3.0/jaxb-impl-2.3.0.jar

下载以上文件并复制到项目的libs文件夹中 在Java Build Path中添加导入的JAR文件

这对我有用，我有一个spring boot项目，在Java 8中编译，但我不知道为什么有一天我的maven开始用Java 11编译，在Ubuntu中我用来修复它:

sudo update-java-alternatives  -l

这显示了我的pc上可用的JDK:

java-1.11.0-openjdk-amd64      1111       /usr/lib/jvm/java-1.11.0-openjdk-amd64
java-1.8.0-openjdk-amd64       1081       /usr/lib/jvm/java-1.8.0-openjdk-amd64`

所以我最后运行这个命令来选择一个想要的:

sudo update-java-alternatives  -s java-1.8.0-openjdk-amd64
