    这个报错 我在android6，7  还有5.0以下都有问题
    但是在小米12 上没问题

网上有些这类方法的解决方案是不对的，大概是通过给主class.dex. 添加报错的的class来实现的，
这个的根本原因是com.qihoo360.replugin.PluginDexClassLoader
installMultiDexesBeforeLollipop 这个方法中

private void installMultiDexesBeforeLollipop(PluginInfo pi, String dexPath, ClassLoader parent) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            return;
        }

        try {

            // get paths of extra dex
            List<File> dexFiles = getExtraDexFiles(pi, dexPath);

            if (dexFiles != null && dexFiles.size() > 0) {

                List<Object[]> allElements = new LinkedList<>();

                // get dexElements of main dex
                //下面这个代码有问题
                //改为：Class<?> clz = getClass()
             //直接在本classLoader中添加dex中的class
             //这个我测试是ok了的 
                Class<?> clz = Class.forName("dalvik.system.BaseDexClassLoader");
                Object pathList = ReflectUtils.readField(clz, this, "pathList");
                Object[] mainElements = (Object[]) ReflectUtils.readField(pathList.getClass(), pathList, "dexElements");
                allElements.add(mainElements);

                // get dexElements of extra dex (need to load dex first)
                String optimizedDirectory = pi.getExtraOdexDir().getAbsolutePath();

                for (File file : dexFiles) {
                    if (LogDebug.LOG && RePlugin.getConfig().isPrintDetailLog()) {
                        LogDebug.d(TAG, "dex file:" + file.getName());
                    }

                    DexClassLoader dexClassLoader = new DexClassLoader(file.getAbsolutePath(), optimizedDirectory, optimizedDirectory, parent);

                    Object obj = ReflectUtils.readField(clz, dexClassLoader, "pathList");
                    Object[] dexElements = (Object[]) ReflectUtils.readField(obj.getClass(), obj, "dexElements");
                    allElements.add(dexElements);
                }

                // combine Elements
                Object combineElements = combineArray(allElements);

                // rewrite Elements combined to classLoader
                ReflectUtils.writeField(pathList.getClass(), pathList, "dexElements", combineElements);

                // delete extra dex, after optimized
                FileUtils.forceDelete(pi.getExtraDexDir());

                //Test whether the Extra Dex is installed
                if (LogDebug.LOG && RePlugin.getConfig().isPrintDetailLog()) {

                    Object object = ReflectUtils.readField(pathList.getClass(), pathList, "dexElements");
                    int length = Array.getLength(object);
                    LogDebug.d(TAG, "dexElements length:" + length);
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

解决方法在注释中写了，由于这个很多人是通过gradle 依赖的远程仓库的，无法改源码，我是通过源码改了之后 ，本地编译，gradle 通过本地引入这个仓库代码解决的
工程的gradle中

   maven{
            url uri('./plugin')
        }
        maven{
            url uri('../plugin')
        }

工程根目录创建plugin文件夹
然后把编译成的pom文件拷本进去，这个自己下载源码编译，就可以了，包括插件和library库

编译过程：
分别打开源码中的插件工程 和lib工程
执行gradle task中的uploadArchives 就可以在对应目录成功了，

  uploadArchives {
       repositories.mavenDeployer {
       //这个是本地生产的目录
           repository(url: "file://${System.getenv('HOME')}/.m2/repository")
           pom.groupId = theGroup
           pom.version = version
           pom.artifactId = pbArtifactId
       }
    }
