嗨,我目前正在使用android studio开发一个android项目。我想使用Paho / Mqtt库,但是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,但是构建仍然显示为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
}
上面的两个解决方案仍然给我留下了同样的56个错误。有人知道在这种情况下该怎么做吗?
最佳答案
这可能不是最佳答案,但是我将版本更改为 1.1.2-SNAPSHOT ,并且构建成功。我看看是否遇到其他错误。让我知道此解决方案是否适合您。
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'
}
}
