arcengine for java将sde里的图层数据导入到gdb

arcengine for java相关环境配置参见我上一篇文章
大概的思路是1、使用gp工具在指定路径创建gdb文件。2、连接上sde(我连接的是oracle)。3、将sde里的表数据导入gdb中。具体代码如下：

 /**
     * 创建gdb文件并将sde里的图层数据导入到gdb中
     * @param gdbPath_          gdb文件的路径，路径不包括 xx.gdb文件
     * @param gdbName           gdb文件的名称，名称包括.gdb后缀
     * @param sdeTableName      sde里表的名称
     * @param attribute         sde里表的数据导入到gdb的限制条件（如 FID=1,多个条件为FID=1 or FID=2 或者是 FID=1 and area=100）
     *                          ,没有就为null(为null的话就将整个图层数据导入gdb)
     */
    public static void sdeToGDB(String gdbPath_ , String gdbName , String sdeTableName , String attribute) throws IOException {
    
    
        //初始换AE
        initializeArcGISLicenses();

        try {
    
    
            /**

            GeoProcessor geoProcessor = new GeoProcessor();
            CreateFileGDB createFileGDB = new CreateFileGDB(gdbPath_ , gdbName);
            geoProcessor.execute(createFileGDB , null);

            String gdbPath = gdbPath_+ File.separator +gdbName;

            /**

            Workspace workspace = connectSde();
