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 

以上就是全部内容，要了解更多内容，请参阅如何使用更新替代命令

你可以使用——add-modules=java.xml。bind JVM选项将xml绑定模块添加到JVM运行时环境。

例如:java——add-modules=java.xml。绑定XmlTestClass

这解决了我在Java 12上运行Apache Camel 2.24.1的依赖关系的问题:

    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>activation</artifactId>
        <version>1.1.1</version>
    </dependency>

    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>2.3.0.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.0.1</version>
    </dependency>

使用JDK 9+时，需要添加JAX-B依赖项。对于Android Studio用户，您需要将此添加到您的构建中。Gradle的dependencies{}块:

// Add missing dependencies for JDK 9+
if (JavaVersion.current().ordinal() >= JavaVersion.VERSION_1_9.ordinal()) {
    // If you're using @AutoValue or any libs that requires javax.annotation (like Dagger)
    compileOnly 'com.github.pengrad:jdk9-deps:1.0'
    compileOnly 'javax.annotation:javax.annotation-api:1.3.2'

    // If you're using Kotlin
    kapt "com.sun.xml.bind:jaxb-core:2.3.0.1"
    kapt "javax.xml.bind:jaxb-api:2.3.1"
    kapt "com.sun.xml.bind:jaxb-impl:2.3.2"

    // If you're using Java
    annotationProcessor "com.sun.xml.bind:jaxb-core:2.3.0.1"
    annotationProcessor "javax.xml.bind:jaxb-api:2.3.1"

    testAnnotationProcessor "com.sun.xml.bind:jaxb-core:2.3.0.1"
    testAnnotationProcessor "javax.xml.bind:jaxb-api:2.3.1"
}

转到您的构建。gradle和添加以下Java 9或Java 10的依赖项。

sourceCompatibility = 10 // You can also decrease your souce compatibility to 1.8 

//java 9+ does not have Jax B Dependents

    compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'
    compile group: 'com.sun.xml.bind', name: 'jaxb-core', version: '2.3.0'
    compile group: 'com.sun.xml.bind', name: 'jaxb-impl', version: '2.3.0'
    compile group: 'javax.activation', name: 'activation', version: '1.1.1'

您需要向maven添加jaxb依赖项。glassfish实现版本2.3.2与新的jakarta EE jaxb api版本2.3.2完全兼容。

<!-- API -->
<dependency>
    <groupId>jakarta.xml.bind</groupId>
    <artifactId>jakarta.xml.bind-api</artifactId>
    <version>2.3.2</version>
</dependency>

<!-- Runtime -->
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>
