我试图在我的项目上执行一个mvn jetty:run，但是，这个过程一直失败，我无法让项目在本地运行。从错误堆栈跟踪来看，我认为需要关注的相关问题是Caused by: java.lang.RuntimeException: Error scanning entry META-INF/versions/9/javax/xml/bind/ModuleUtil.class from jar file:///C:/Users/Tabish/.m2/repository/javax/xml/bind/jaxb-api/2.3.0/jaxb-api-2.3.0.jar。我试过改变jaxb的版本，但没有结果。

这是错误跟踪

我正在使用jdk-11.0.2运行。我的pom.xml有以下的依赖项和jetty插件(我认为是其中之一导致了问题)

  1. 通过引用jaxb/2.3.0的pom，目标jdk版本为9。
  2. 通过找到jetty-注释/9.3.7.v20160115的依赖项，“org.ow2.asm”的依赖项是5.0.1，因为JDK 9将于2017年9月发布，因此可以确定asm库不支持java 9，我们也可以参考ClassReader的源代码
代码语言：javascript
运行
复制
public class ClassReader {
...
    /**
     * Constructs a new {@link ClassReader} object.
     * 
     * @param b
     *            the bytecode of the class to be read.
     * @param off
     *            the start offset of the class data.
     * @param len
     *            the length of the class data.
     */
    public ClassReader(final byte[] b, final int off, final int len) {
        this.b = b;
        // checks the class version
        if (readShort(off + 6) > Opcodes.V1_8) {
            throw new IllegalArgumentException();
        }
...
}

我们看到，如果类版本晚于1.8，则检查该类版本。下面的程序显示了如何检查jar是否包含ClassReader不支持的类。

import java.io.ByteArrayOutputStream;

public class ClassReaderJarVersionCheck {
    public static void main(String[] args) throws FileNotFoundException, IOException {
        checkClassVersion();
    }

    private static void checkClassVersion() {

        String jarPath = "{path_to_jar}\\jaxb-api-2.3.0.jar";
        try (JarFile jarFile = new JarFile(jarPath)) {
            jarFile.stream().forEach(jarEntry -> {
                if (jarEntry.isDirectory() || !jarEntry.getName().endsWith(".class")) {
                    return;
                }
                int version = -1;
                try {

                    version = readShort(byteArray, 6);
                    new ClassReader(byteArray);
                } catch (IOException e) {
                    throw new RuntimeException(e);
                } catch (IllegalArgumentException e) {
                    System.out.println(jarEntry.getName() + " version: " + version);
                }
            });
        } catch (IOException ioe) {
            throw new RuntimeException(ioe);
        }
    }

    private static short readShort(byte[] b, int index) {
        return (short) (((b[index] & 0xFF) << 8) | (b[index + 1] & 0xFF));
    }

    private static byte[] toByteArray(InputStream is) throws IOException {
        ByteArrayOutputStream buffer = new ByteArrayOutputStream();
        int nRead;
        byte[] data = new byte[1024];
        while ((nRead = is.read(data, 0, data.length)) != -1) {
            buffer.write(data, 0, nRead);
        }
        buffer.flush();
        byte[] byteArray = buffer.toByteArray();
        return byteArray;
    }
}

解决方案

JDK>=11升级Jetty

通过引用码头9.4.12发布公告，将jetty的依赖项更新为版本9.4.12以支持JDK 11应该可以解决这个问题。

降级jaxb-api用于JDK 8

使用2.2.11版本作为下一个版本2.3.0开始采用JDK 9
