破解 DVT 25.1.8

前言

DVT IDE 作为 Eclipse 和 VSCode 的插件，有 DVT Eclipse 和 DVT VSCode 两类。
DVT Eclipse 25.1.8 有 Linux x64、Linux arm64、macOS arm64 以及 Windows x64等版本
- 解压 DVT Eclipse 的 zip 安装包，得到dvt_eclipse文件夹
- 将DVT_HOME环境变量设置为解压后的dvt_eclipse目录
- 在 Linux 平台，运行$DVT_HOME/bin/dvt.sh打开DVT Eclipse
- 在 Windows 平台，运行$DVT_HOME/bin/dvt.bat打开DVT Eclipse

DVT VSCode 可直接从 VSCode 的插件市场安装

破解

破解 DVT IDE 主要分为两个步骤：
- 破解ro.amiq.dvt.flclient-2.21.jar文件
- 将DVT_LICENSE_FILE环境变量设置为dvt.lic文件的路径（dvt.lic内容见附录）
对于 DVT Eclipse
- ro.amiq.dvt.flclient-2.21.jar文件存在以下两个目录，只需破解其中一个，并将破解后的ro.amiq.dvt.flclient-2.21.jar放入相应的目录即可。
- 破解之前，应该先运行dvt.sh，将第二个目录的ro.amiq.dvt.flclient-2.21.jar释放出来。
- 由于第二个目录的ro.amiq.dvt.flclient-2.21.jar位置不固定，故可使用命令find $DEV_HOME -name ro.amiq.dvt.flclient-2.21.jar进行查找。
- 文件路径
  - dvt_eclipse/batch/libs/ro.amiq.dvt.flclient-2.21.jar
  - dvt_eclipse/eclipse/configuration/org.eclipse.osgi/304/0/.cp/libs/ro.amiq.dvt.flclient-2.21.jar
对于 DVT VSCode
- ro.amiq.dvt.flclient-2.21.jar文件存在一个位置，只需将破解的ro.amiq.dvt.flclient-2.21.jar替换原来的文件即可。
- 文件路径
  - ~/.vscode-server/extensions/amiq.dvt-25.1.8-linux-x64/dvt_home/common/batch/libs/ro.amiq.dvt.flclient-2.21.jar

- 依次点击File->Load，加载ro.amiq.dvt.flclient-2.21.jar

定位目标代码

依次点击Search->Values，使用-515、-514等值确定要修改的文件
展开搜索到的函数，右击函数并点击"Goto definition"

若代码如下所示，则为目标代码（目标函数public static boolean a(byte[] byArray, byte[] byArray2, k object, int n)）

反编译目标函数

在目标函数区域右键选择Edit with assembler
在弹出窗口的汇编代码开头添加如下指令，并Ctrl+S保存文件
```
ICONST_1
IRETURN
```

再次回到目标代码，其文件内容变为

// Decompiled with: CFR 0.152
// Class Version: 8
package com.a.a.e;
import com.a.a.a.s;
import com.a.a.e;
import com.a.a.g;
import com.a.a.k;
/*

 */
public class l
implements g {
    private static String a;
    public static boolean a(byte[] byArray, byte[] byArray2, k k2, int n) {
        return true;
    }
    @Override
    public String a() {
        return System.getProperty("user.name");
    }
    @Override
    public String b() {
        return s.f();
    }
    @Override
    public String c() {
        return "JavaDisplay";

    @Override
    public int a() {
        return 255;
    }
    @Override
    public void a(e e2) {
    }
}
