解决自构建 CoreProtect 无法启动的问题

发表于 Waline：

我最近在尝试Minecraft 1.21服务端的兼容性，CoreProtect一直是一个很重要的插件，可以帮助玩家和管理员查询方块的更改记录，以便监管和阻止恶意破坏行为。

CoreProtect的最新构建是需要付费的，但它的源代码在它的 GitHub 仓库上开源，所以我们理所应当地想到了手动构建。然而，在手动构建之后，却出现了意料之外的报错。

日志显示：To continue, set project branch to "development"。由此得知，需要把branch设置为development才可以正常运行。

那么，如何设置branch呢？

我们回到CoreProtect的源码中继续寻找，找到了下面这部分代码

net.coreprotect.config.ConfigHandler (1-55行)

public class ConfigHandler extends Queue {

    public static final int EDITION_VERSION = 2;
    public static final String EDITION_BRANCH = Util.getBranch();
    public static final String EDITION_NAME = Util.getPluginName();

我们可以看到，这里有一个常量叫做EDITION_BRANCH，是通过Util.getBranch方法获取的。所以我们可以把这个常量直接设置为development，以解决这个问题。

public static final String EDITION_BRANCH = "development";

设置完毕之后，插件便可以正常运行了。
