[英]Building Cordovo Android app fails - Dex cannot parse version 52 byte code error message
我正在嘗試構建一個Cordova Android應用程序,當我嘗試使用調用cordova build
命令的自定義腳本進行cordova build
,出現以下錯誤-這可能是什么嗎?
Dex: Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.

我在Windows 10 Pro上使用以下命令:-
javac -version
javac 1.8.0_221
javaw -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
NodeJS : v10.13.0
npm : 6.7.0
Gradle是截至02/09/2019的最新版本,是gradle-5.6.1
內容為:
ParseException: bad class file magic (cafebabe) or version (0034.0000)
0x0034
是版本52字節代碼,這意味着某個類已使用JDK 8進行了編譯,該版本的dex
無法理解。 它甚至明確要求源/目標兼容模式:
Dex: Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
因此,有兩種選擇:
a)遵循建議並編輯compileOptions
(這不僅適用於java
插件):
android {
compileOptions {
// sourceCompatibility JavaVersion.VERSION_1_6
// targetCompatibility JavaVersion.VERSION_1_6
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
b)使用JDK 8進行構建。
您實際上正在使用相當舊的版本進行構建:
dependencies {
classpath "com.android.tools.build:gradle:2.2.3"
}
task wrapper(type: Wrapper) {
gradleVersion = "2.14.1"
}
而當前版本是:
dependencies {
classpath "com.android.tools.build:gradle:3.5.0"
}
task wrapper(type: Wrapper) {
gradleVersion = "5.4.1"
}
當我閱讀2.2.3
版本時,我會假設Android Studio的版本與舊版本相同。 更新至Android Studio 3.5.0
並安裝了嵌入式JRE 8。 該Android Studio可能仍然具有嵌入式JRE 7(無論路徑上聲稱的JDK是什么,因為全局JDK和嵌入式JRE是兩個不同的安裝)。 Gradle也是如此,因為它可能會使用2.14.1
版的本地包裝程序,而不是5.6.1
版的全局安裝程序。 可以告訴Gradle將特定的JDK與org.gradle.java.home
一起使用,但是IDE通常可能太舊了。 您至少需要Android Studio 3.0.0才能支持Java 8。
