您可以使用这个依赖项

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

好吧，我一直有同样的问题，但我使用的是Java 8，并不断得到这个错误，我尝试了大多数的解决方案。但事实证明，我的maven仍然指向java 9，即使我将全局java版本设置为8，只要我修复了它就能正常工作。

对于任何可能遇到这类问题的人，请参阅如何修复Maven以使用默认Java(已存档)

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>

对于我来说，Eclipse 2020-12(4.18.0)正在使用inbuild (org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_15.0.1.v20201027-0507\jre)

在安装的JREs(这是我想要的)中将java更新到1.8后解决了这个问题。

希望能有所帮助。

由于JavaEE现在由https://jakarta.ee/管理，因此2.3.2的新Maven坐标为:

https://eclipse-ee4j.github.io/jaxb-ri/#maven-artifacts

第一个发布的jaxb。版本为2.3.2。

<properties>
  <jaxb.version>2.3.2</jaxb.version>
</properties>

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>${jaxb.version}</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>${jaxb.version}</version>
</dependency>

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!
