Question

我想知道我做错了什么，或者我是否偶然发现了LibGDX / GWT中的错误。我有一个桌面/ Android / iOS / HTML后端的游戏，并从大约一个月前从1.9.5-SNAPSHOT升级到1.9.5使HTML构建停止工作。我能看到的主要变化是从2.6.0升级到GWT 2.8.0。

当我在浏览器中运行我的应用程序（Windows 10上的Chrome 56.0.2924.21 beta（64位））时，出现以下错误：

GwtApplication: exception: com.badlogic.gdx.utils.SerializationException: Error reading file: static/uiskin_hd.json
com.badlogic.gdx.utils.SerializationException: Error reading file: static/uiskin_hd.json
Error reading file: static/uiskin_hd.json

Error loading bitmap font: static/helsinki28plain_hd.fnt
Error loading font file: static/helsinki28plain_hd.fnt
Invalid page id: 
For input string: ""

该字体以前一直在工作，我得到的结果与任何字体相同，包括来自LibGDX测试的default.fnt。字体文件的顶部如下所示：

info face="Helsinki" size=56 bold=0 italic=0 charset="" unicode=0 stretchH=100 smooth=1 aa=1 padding=2,2,8,4 spacing=0,0
common lineHeight=75 base=52 scaleW=512 scaleH=1024 pages=1 packed=0
page id=0 file="helsinki28plain_hd.png"
chars count=141
char id=32   x=0     y=0     width=0     height=0     xoffset=0     yoffset=52    xadvance=22     page=0  chnl=0 
char id=92   x=0     y=0     width=24     height=72     xoffset=-2     yoffset=0    xadvance=22     page=0  chnl=0 
char id=47   x=24     y=0     width=24     height=72     xoffset=-2     yoffset=0    xadvance=22     page=0  chnl=0 
...

为了确保问题不在我的设置中，我检查了LibGDX的最新主分支并尝试运行GWT测试：

git clone https://github.com/libgdx/libgdx.git
cd libgdx
ant -f fetch
ant
./gradlew tests:gdx-tests-gwt:draftRun

这似乎也失败了：

有什么想法在这里发生了什么？（我的Java SDK是jdk1.8.0_20）

看起来这是LibGDX 1.9.5中的一个错误。有几个人已经提交拉动请求来修复它，所以我预计很快会有一个1.9.6-SNAPSHOT可以解决这个问题。
