使用 jfxmobile-plugin 为 Android 编译 JavaFX Undertow Websockets 项目时属性被严重截断

Question

我在为 Android 编译 JavaFX 项目时遇到问题。该项目包括一堆库，Undertow Websockets 就是其中之一。我将所有需要的 jar 下载到我的 lib 目录，并将它们包含到 build.gradle 文件的依赖项/编译文件块中。

我能够解决 jar 文件依赖项的其他问题（主要是 DuplicateFileException），但是一个 Undertow 库 - undertow-core-1.3.14.Final.jar 给了我有点头疼。

当我将它添加到 编译文件 块的 gradle.build 文件‘gradlew android’时，给我一条错误消息：

What went wrong: Execution failed for task ‘:createMainDexList’.

Exception in thread “main” com.android.dx.cf.iface.ParseException: severely truncated attribute at com.android.dx.cf.direct.StdAttributeFactory.throwSeverelyTruncated(StdAttributeFactory.java:736) at com.android.dx.cf.direct.StdAttributeFactory.runtimeVisibleParameterAnnotations(StdAttributeFactory.java:661) at com.android.dx.cf.direct.StdAttributeFactory.parse0(StdAttributeFactory.java:162) at com.android.dx.cf.direct.AttributeFactory.parse(AttributeFactory.java:96) at com.android.dx.cf.direct.AttributeListParser.parse(AttributeListParser.java:141) at com.android.dx.cf.direct.AttributeListParser.parseIfNecessary(AttributeListParser.java:115) at com.android.dx.cf.direct.AttributeListParser.getEndOffset(AttributeListParser.java:96) at com.android.dx.cf.direct.MemberListParser.parse(MemberListParser.java:213) at com.android.dx.cf.direct.MemberListParser.parseIfNecessary(MemberListParser.java:108) at com.android.dx.cf.direct.MethodListParser.getList(MethodListParser.java:54) at com.android.dx.cf.direct.DirectClassFile.parse0(DirectClassFile.java:542) at com.android.dx.cf.direct.DirectClassFile.parse(DirectClassFile.java:406) at com.android.dx.cf.direct.DirectClassFile.parseToEndIfNecessary(DirectClassFile.java:397) at com.android.dx.cf.direct.DirectClassFile.getAttributes(DirectClassFile.java:311) at com.android.multidex.MainDexListBuilder.hasRuntimeVisibleAnnotation(MainDexListBuilder.java:191) at com.android.multidex.MainDexListBuilder.keepAnnotated(MainDexListBuilder.java:167) at com.android.multidex.MainDexListBuilder.(MainDexListBuilder.java:121) at com.android.multidex.MainDexListBuilder.main(MainDexListBuilder.java:91) at com.android.multidex.ClassReferenceListBuilder.main(ClassReferenceListBuilder.java:58) …while parsing RuntimeVisibleParameterAnnotations attribute at offset 0009c07 > …while parsing attributes[3] …while parsing methods[1] …while parsing io/undertow/client/http/HttpResponseParser$$generated.class

有没有人设法用 Undertow Websockets 生成 apk，或者遇到与第 3 方库类似的问题？

如有任何帮助，我们将不胜感激。谢谢！

我已经能够重现您发布的相同错误，只需使用此依赖项和运行ning ./gradlew android:

dependencies {
    compile ('io.undertow:undertow-servlet:1.3.19.Final') {
        exclude group: 'org.jboss.spec.javax.annotation' 
    }
    compile ('io.undertow:undertow-core:1.3.19.Final') {
        exclude group: 'org.jboss.spec.javax.annotation' 
    }
    compile ('io.undertow:undertow-websockets-jsr:1.3.19.Final') {
        exclude group: 'org.jboss.spec.javax.annotation' 
    }
}

所以为了找出可能的问题，我从 here 下载了 io.undertow` 源，添加了所需的依赖项（也许我没有使用确切的版本） :

dependencies {
    compile 'org.jboss.logging:jboss-logging-annotations:2.0.1.Final'
    compile 'org.jboss.classfilewriter:jboss-classfilewriter:1.0.4.Final'
    compile 'org.eclipse.jetty.alpn:alpn-api:1.0.0'
    compile 'org.jboss.xnio:xnio-nio:3.3.4.Final'
    compile 'org.jboss.xnio:xnio-api:3.3.4.Final'
    compile 'org.jboss.logging:jboss-logging:3.2.1.Final'
    compile 'org.jboss.spec.javax.websocket:jboss-websocket-api_1.1_spec:1.1.0.Final'
    compile 'org.jboss.spec.javax.servlet:jboss-servlet-api_3.1_spec:1.0.0.Final'
}

为了避免与 javax.annotation 重复类，我从 here 下载了 org.jboss.spec.javax.annotation:jboss-annotations-api_1.1_spec 的源代码，并删除了这三个类： Generated.java、PostConstruct.java 和 PreDestroy.java。

我能够运行 ./gradlew android 成功，但我还没有测试过。

如果您仍然无法构建它或稍后运行将其安装到设备上，也许您可以考虑其他 websockets 替代方案，例如 Tyrus 项目。

这是一个 project 我们已经成功使用它。
