问题描述
我正在使用libgdx在Android Studio 3.1中创建一个项目，我无法构建我的项目，因为它说：
I'm making a project in Android Studio 3.1 with libgdx and i can't build my project because it says:
class "org.bouncycastle.jcajce.provider.symmetric.IDEA$Mappings"'s signer information does not match signer information of other classes in the same package
但我不使用bouncycastle或某些东西
我检查了很多关于这个问题的页面和主题，但我没有找到任何解决方案。此外，我没有任何jar文件，我从来没有尝试签署的东西，我只是想建立我的项目
请帮助我们，我真的坚持它
But i don't use "bouncycastle" or somethingI checked a lot pages and topics about this problem but i didn't find any solutions for this. Also i haven't any jar files and i never tried to sign something, i'm only trying to build my projectPlease help me guys, i really stuck at it
推荐答案
更新：Java 10.0.2遇到GDX 1.9.8问题所以我降级到Java 8，一切都按预期工作。如果您安装了最新的Java 10，请卸载并下载并安装java 8版本。
Update: Java 10.0.2 was having issues with GDX 1.9.8 so I downgraded to Java 8 and everything is working as expected. If you installed the latest Java 10, uninstall and download and install the java 8 version.
旧评估：
我最近遇到了android 3.1.4和当前版本的libgdx（jar下载于09 / xx / 2018）的这个问题。
I've recently encountered this issue with android 3.1.4 and a current version of libgdx(jar downloaded on 09/xx/2018).
环境：新安装的Windows 7 Ultimate + sp1 +便捷汇总，gdx-setup.jar（九月xx，2018），+ Android Studio 3.1.4（全新安装） ，java 10.0.2。
Environment: Freshly installed Windows 7 Ultimate + sp1 + convenience rollup, gdx-setup.jar(September xx, 2018), + Android Studio 3.1.4(clean install), java 10.0.2.
问题转载：gdx-setup.jar用我更新的build-tools+api制作了一个项目，但项目没有在Android Studio中编译并产生最初发布的错误。
Problem reproduced: gdx-setup.jar with my updated "build-tools" + "api" produced a project, but the project did not compile in Android Studio and produced the error originally posted.
进程：gdx-setup.jar及其默认构建工具（27.0.3）和默认api（27）将产生关于不正确的api 28> 27的错误，这可能与某些不相关，但Android Studio 3.1.4的新安装可能会遇到此问题。使用Android studio sdk-manager（工具选项卡）并下载了27.0.3 build-tools和sdk-tools（确保检查显示包详细信息的可见性）。安装上面的内容并在默认情况下重新运行gdx-set.jar后，我就可以生成项目，甚至可以在Android工作室上编译/运行。
Process: gdx-setup.jar with its default build-tools(27.0.3) and default api(27) will produce an error about incorrect api 28 > 27, which may not be relevant to some, but new installations of Android Studio 3.1.4 may encounter this. Used Android studio sdk-manager(tools tab) and downloaded 27.0.3 build-tools and sdk-tools (make sure the "Show package details" is checked for visibility). After installing the above and rerunning gdx-set.jar on defaults, I was able to produce the project and even compile/run on Android studio.
GDX的临时解决方案（ 2018年9月）：确保Android Studio具有：build-tools 27.0.3 + sdk-tools 27，并使用工具的默认值创建gdx项目（创建gdx项目时两个提示都没有。）
Temporary Solution for GDX(September 2018): Ensure Android Studio has: build-tools 27.0.3 + sdk-tools 27, and create the gdx project using defaults for tools (No to both prompts when creating gdx project).
