Question

我正在尝试使用以下库读取加密的Access .mdb：

Jackcess-2.1.6
Jackcess-encrypt-2.1.2
Ucanaccess-4.0.2
bcprov-jdk15on-157

按照Ucanaccess's documentation简单地实现JackcessOpenerInterface：

public class CryptCodecOpener implements JackcessOpenerInterface {
    public Database open(File fl, String pwd) throws IOException {
        DatabaseBuilder dbd =new DatabaseBuilder(fl);
        dbd.setAutoSync(false);
        dbd.setCodecProvider(new CryptCodecProvider(pwd));
        dbd.setReadOnly(false);
        return dbd.open();

    }
}

我得到以下异常：

Exception in thread "main" java.lang.NoClassDefFoundError: net/sourceforge/cobertura/coveragedata/TouchCollector
    at com.healthmarketscience.jackcess.CryptCodecProvider.__cobertura_init(CryptCodecProvider.java)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

从我收集的内容来看，Cobertura是Java的代码覆盖实用程序。这只是一个坏罐子还是我做错了什么？

使用Jackcess抛出代码覆盖异常读取加密的Access .mdb
