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

分类: 技术问答 • 2022-09-28 00:25:05
问题描述：

您好我目前正在使用android studio的一个android项目。我想使用Paho/Mqtt库，但在构建时似乎遇到问题。
这些都是在的build.gradle文件错误：警告：忽略Paho/Mqtt的匿名内部类的InnerClasses属性

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个差错的相关要素，但构建仍显示为BUILD成功的。

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.

我试图通过在我的proguard的加入修复此错误的日志-rules.pro文件

-keepattributes InnerClasses 
-keepattributes EnclosingMethod 
-dontoptimize

除了在的defaultConfig块这些线路的build.gradle文件

compileOptions { 
     sourceCompatibility JavaVersion.VERSION_1_7 
     targetCompatibility JavaVersion.VERSION_1_7 
}

两个以上的解决方案仍然给我留下了相同的56个错误。有人会知道在这种情况下要做什么吗？

答

这可能不是最佳答案，但是我将版本更改为1.1.2-SNAPSHOT并且构建实际上是成功的。我会看看我是否遇到任何其他错误。让我知道这个解决方案是否适合你。

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' 
    } 
}
