This may be gradle-related, as it's also happening when trying to run tests from the command line. Here's a stack trace:

Another test fails due to not finding 'Parcelable'. The tests were running fine (tm) yesterday. I also made a change to the build.gradle files, adding a dependency, but reverting that change doesn't help. Also, doing './gradlew --stop' did not have any impact. I will report this now and continue to try to find a way to make the tests run again.

This is also using AGP 3.0.0-beta4.

Could it be a Gradle plugin issue?

pe...@gmail.com <pe...@gmail.com> #4Sep 5, 2017 07:21AM

In 3.2.0-alpha02 we started compiling against android.jar and core-lambda-stubs.jar (coming from build tools). Previously, we were compiling against JDK and android.jar which could lead to some issues.

It might be that android.jar is corrupted or android.jar is missing altogether. Is the command from #1 what you use to download the SDK on the CI? Also, can you please check if $ANDROID_HOME/platforms/android-27/android.jar on the CI contains java/lang classes?

Yes, the command in #1 is what I used to download the SDK on the CI.

$ANDROID_HOME/platforms/android-27/android.jar is 29514833 bytes with a SHA256SUM of ab3f5a358b25b203e4678a5dc7b0e442f4fd1ccfeb6e29914d46d4c8ead22c9a and it contains a java/lang directory with about 160 files/directories inside of it.

Does the build pass on the CI, if you specify add android.enableCoreLambdaStubs=false to gradle.properties file?

jo...@google.com <jo...@google.com> #7Sep 14, 2017 08:09PM

Also, which JDK version are you using on the CI? What is the output of `java -version`?

be...@google.com <be...@google.com> #8Sep 15, 2017 09:13AM

I get the same error with the enableCoreLambdaStubs flag set to false: ":app:compileJunitReleaseJavaWithJavacFatal Error: Unable to find package java.lang in classpath or bootclasspath"

`java -version` gives:

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

Android SDK SHA and java in the $PATH look good. Are you setting JAVA_HOME to JDK9 in the CI script? Can you please share your build files and CI script?

Marked as fixed.

To check which version of JVM is used when building with Gradle, you can add the following to build.gradle:

println "Java version is ${JavaVersion.current()}"
