minecraft forge gradle“runClient”异常

Question

我应该安装minecraft forge。我写gradle命令。

gradlew setupDecompWorkspace
gradlew eclipse

该命令运行良好。

但下一个命令不起作用

gradlew runClient

这是命令的例外。

What can I do??

Also gradlew build is well.

Answer 1

如果您正在使用ForgeGradle 3进行修改，您现在可以运行客户端，因为ForgeGradle 3已更新。

如果您没有使用ForgeGradle 3. x进行修改，则无法使用官方ForgeGradle进行修改。伪造开发者组永远不会修复它。（见https://github.com/MinecraftForge/ForgeGradle/issues/652）

您可以使用ForgeGradle的叉或ForgeGradle的叉。

我用ForgeGradle 2.3和1.2制作了叉子，这样你就可以使用它们了。（如果对我的叉子有疑问，请在叉子上发表意见。）如果你用的是不是2.3或1.2的ForgeGradle，或者你不想用我的叉子，你可以用ForgeGradle做叉子。

此崩溃的原因代码是GradleStart中的hackNatives（）函数。hackNatives函数设置ClassLoader。重置类加载器的系统路径null。usr_路径。

直到8u242，ClassLoader。loadLibrary检查sys\u path是否为null，如果sys\u path为null则重置sys\u path和usr\u path。

但是由于8u242，当启动JVM和类加载器时，sys_路径和usr_路径被初始化。loadLibrary从不检查sys\u path是否为null。（见http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/1d666f78532a/)

我们必须在hackNatives（）中重写GradleStart类，在参考资料目录中有。要重置usr\u路径，请执行usr\u路径=initializePath（“java.library.path”），并在hackNatives（）中进行反射。（您可以在minecraft forge 1.15.x userdev:LaunchTesting.java#L126中引用黑客）
