Recently, I was researching the TDD development model. After setting up the framework, I found that the compilation error was reported. After some fiddling around, the problem was solved. Then record it, I hope it will be helpful to the students who also encounter this problem.
Error:Execution failed for task ':app:transformClassesWithDexForDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1
Inexplicable error, no solution ideas. So I searched on the Internet and referenced a number of solutions but did not solve the problem.
But the search process is still rewarding:
-
For the convenience of testing, I created a new Java Library project to store classes that do not depend on the Android system. Then add it to app/build.gradle as a dependency.
dependencies {
...
compile project(':core')
}
-
When I removed this line of code, I found that it could be compiled and passed, which means that the problem lies in the dependency on the library.
-
In the process of searching for solutions, I found that most of the people who encountered such problems were using the JDK 1.8 version (I believe you should also notice which version I am using, if not, please look up and have a look ^_ ^). This is not a coincidence, so I suspect Gradle has compatibility issues with JDK 1.8. Try to reduce the JDK version that the project depends on to 1.7, try to compile again, success!
Small summary:
Gradle is still in the active development period, and many new versions have unstable functions. It is recommended to update the Gradle version used by the project with caution.
