created issue #1

Aug 9, 2017 06:49PM

STEPS TO REPRODUCE
1. Create a module using Java 1.8 and lambdas, and add an instrumentation test
2. Enable coverage
3. Run the tests

RESULTS

Also try building the app with proguard, which will fail due to the same missing class

It's also happening at runtime for some users.

Using code
Timber.e(new IllegalStateException("haha"), "test");
in Application.onCreate()

This is preventing us from running our Espresso tests. At first I thought it was something to do with Dex files not including the correct desugar classes. But what I do know is that the Espresso tests run with gradle plugin 3.0.0-alpha9 and do not run with 3.0.0-beta1.

Seeing the Jacoco part of the stacktrace led me down a path to remove the unit test coverage lines I'd added to my build.gradle, which led to a slightly smaller stacktrace:

I should also mention that this exception was also occurring at runtime preventing the app from starting up.

[Deleted User] <[Deleted User]> #5Aug 9, 2017 10:47PM

Stacktrace of crash at runtime is similar:

08-09 16:41:56.396 E/AndroidRuntime: FATAL EXCEPTION: main
Process: ca.company.android.selfserve.tst, PID: 10043

at timber.log.Timber.i(Timber.java:56)
at com.company.selfserve.presentation.base.concurrency.threadqueue.LifecycleAwareUiThreadQueue.run(LifecycleAwareUiThreadQueue.java:43)

The code at that line is:

Timber.i(new Exception(), "Deferred running a runnable due to bad lifecycle state: %s", lifecycle.getCurrentState().toString());

I believe it is simply calling new Exception() that causes the crash.

ja...@google.com <ja...@google.com> #6Aug 9, 2017 10:50PM

The cause is Timber's use of Throwable.printStackTrace(PrintWriter) in the getStackTraceString method.

[Deleted User] <[Deleted User]> #7Aug 9, 2017 10:56PM

Right. The stacktrace doesn't lie. ;)

not using Timber, not running espresso tests with coverage. Still seeing error and hanging

Temporary workaround is to set min sdk version below 19. Issue is that Desugar will process try-with-resources for API 19+, although platform supports it, but we will not package those classes.

If you implement the `HotFix` found in the answer in

https://stackoverflow.com/questions/45604099/rxjavaplugins-error-didnt-find-class-com-google-devtools-build-android-desugar
the app will compile, but tests cannot be found:

I am not sure, if this is related to the bug mentioned here, or another 3.0-beta1 issue.

```

No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test
annotations).

Using the workaround minSdk < 19 leads to Android Studio finding my tests. So the above comment is related to this issue.

For anyone using Kotlin. Removing compiling options for java 8 will work. We had some problem building release apks. We commented java 8 options in build.gradle file. We are using full kotlin so we will not lose lambdas, and we were ok with it.

ga...@google.com <ga...@google.com> #17Aug 10, 2017 04:08PM

Marked as fixed.

Fix will land in plugin 3.0.0-beta2. As mentioned in #12, current workaround is to set min sdk below 19. Alternatively, you can disable support for Java 8 language features.

Ivan, can you point me to the CL that caused this in the first place? We'd like to do a post-mortem and find out how this was introduced and then not caught in automated or manual testing and then made it into the release.

ga...@google.com <ga...@google.com> #19Aug 11, 2017 11:13AM

I've started a doc, go/desugar-3.0.0-beta1-postmortem, that contains info on that. Free free to edit it, or to start a new one.

I was running in to a very similar issue while using AS beta2. I was able to work around the issue by reverting to AS beta1, while still using the beta2 plugin.

My minSdk is 21 and changing to 18 did not work.
Removing java8 features wasn't an option.
Tried reinstalling beta2 before reverting with no success.
My app was crashing on launch with missing class/file exceptions when using proguard.

The bug is _not_ fixed in Beta 3.
I just got this error and was able to use workaround setting minSdk to 18
I do use Java 8 features
I do use try with resources

The issue is back in Beta3

Status: Assigned (reopened)

I can confirm that the issue is back. Master is ok, but it looks like the fix did not end up in 3.0.0-beta3 release (although it is present in 3.0.0-beta2). I am trying to figure out what happened.

ga...@google.com <ga...@google.com> #24Aug 25, 2017 08:54AM

Workaround is to set min sdk below 19, or to disable Java 8 language support. Sorry for hitting this issue once again. We will release a new version with the fix as soon as possible.

It looks like the following happened:
1) fix for this bug was cherry-picked to the release branch, and we released 3.0.0-beta2 with the fix.
2) release branch then got reset to build number 4261210 from studio-master-dev. The fix got into studio-master-dev in build 4263002, so release branch dropped the fix from 1).
3) all future cherry-picks did not touch this part of code, and we had no cherry-pick conflicts that would point out this issue.

I also have this bug.
I've several codes are written in Java 8 () I can't just go and disable it.
Why we can't use Gradle plugin 3.0.0-beta2 with and android studio 3.0 beta 3?

te...@gmail.com <te...@gmail.com> #26Aug 25, 2017 02:57PM

As stated in #24 you can set minSdk to 18 or less.
Also, in this StackOverflow answer you have an alternative workaround:

Also, Android O fonts API does not work for me as stated in

Marked as fixed.

fixed in beta4.

When can we expect beta 4 to release?

st...@gmail.com <st...@gmail.com> #32Aug 30, 2017 03:41PM

This was affecting my release builds on trying to find ThrowableExtension. After adding ThrowableExtension.java as the work around like stated here:

https://stackoverflow.com/a/45609518/468360 everything worked as expected. Setting my SDK min to < 19 was simply not an option for me.

I am working on Android studio 3.0.1 and using classpath 'com.android.tools.build:gradle:3.0.1' and still running into same issue. Is there another thread where this issue has been fixed? Here is my error:
