Failed to install android-sdk: "java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema"

The java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema error can occur if the required Java XML Binding (JAXB) classes are not present on the classpath.

To fix this error, you need to include the JAXB API in your project. The JAXB API is included in the Java SE Development Kit (JDK) as part of the Java Standard Edition (SE). If you are using an older version of the JDK that does not include the JAXB API, you can download the JAXB API separately and include it in your project.

To include the JAXB API in your project, you need to add the following dependencies to your build file (e.g., build.gradle):

dependencies {
    compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'
    runtime group: 'com.sun.xml.bind', name: 'jaxb-impl', version: '2.3.1'
}

Replace 2.3.1 with the version of the JAXB API that you want to use.

I hope this helps. Let me know if you have any questions.
