错误：警告：忽略Paho / Mqtt的匿名内部类的InnerClasses属性

标签： android gradle paho

您好我正在使用android studio进行Android项目。我想使用Paho / Mqtt库，但我在构建时似乎遇到了问题 这些是 build.gradle 文件

中的相关元素 
repositories {
    jcenter()
    maven {
        url "https://repo.eclipse.org/content/repositories/paho-snapshots/"
    }
}

dependencies {
    compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.1'
    compile('org.eclipse.paho:org.eclipse.paho.android.service:1.1.1') {
        exclude module: 'support-v4'
    }
}

有56个错误，但构建仍显示为BUILD SUCCESSFUL。

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:(org.eclipse.paho.client.mqttv3.MqttAsyncClient$1) that doesn't come with an
Error:associated EnclosingMethod attribute. This class was probably produced by a
Error:compiler that did not target the modern .class file format. The recommended
Error:solution is to recompile the class from source, using an up-to-date compiler
Error:and without specifying any "-target" type options. The consequence of ignoring
Error:this warning is that reflective operations on this class will incorrectly
Error:indicate that it is *not* an inner class.

我尝试通过添加 proguard-rules.pro 文件来修复此错误

-keepattributes InnerClasses
-keepattributes EnclosingMethod
-dontoptimize

以及 build.gradle 文件的 defaultConfig 块中的这些行

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
}

上述两个解决方案仍然给我留下了相同的56个错误。有谁知道在这种情况下该怎么做？

1 个答案:

答案 0 :(得分：0)

这可能不是最佳答案，但我将版本更改为 1.1.2-SNAPSHOT ，并且构建实际上已成功。我会看到是否遇到任何其他错误。如果此解决方案适合您，请告诉我。

dependencies {
    compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.2-SNAPSHOT'
    compile('org.eclipse.paho:org.eclipse.paho.android.service:1.1.2-SNAPSHOT') {
        exclude module: 'support-v4'
    }
}
