Gradle: Could not determine java version from '11.0.2'

Solution 1

There are two different Gradle applications in your system.

the system-wide Gradle
This application is invoked by gradle (arguments).
the gradle-wrapper
The gradle-wrapper is specific to every project and can only be invoked inside the project's directory, using the command ./gradlew (arguments).

Your system-wide gradle version is 5.1.1 (as the OP explained in the comments, running the command gradle --version returned version 5.1.1).

However, the failure is the result of a call to the gradle-wrapper (./gradlew). Could you check your project's gradle wrapper version? To do that, execute ./gradlew --version inside your project's folder, in the directory where the gradlew and gradlew.bat files are.

Update 1:
As running ./gradlew --version failed, you can manually check your wrapper's version by opening the file:

(project's root folder)/gradle/wrapper/gradle-wrapper.properties

with a simple text editor. The "distributionUrl" inside should tell us what the wrapper's version is.

Update 2: As per the OP's updated question, the gradle-wrapper's version is 4.1RC1.
Gradle added support for JDK 11 in Gradle 5.0. Hence since 4.1RC does not support running on JDK 11 this is definitely a problem.

The obvious way, would be to update your project's gradle-wrapper to version 5.0.
However, before updating, try running gradle app:installDebug. This will use your system-wide installed Gradle whose version is 5.1.1 and supports running on Java 11. If this works, then your buildscript (file build.gradle) is not affected by any breaking changes between v.4.1RC1 and v.5.1.1 and you can then update your wrapper by executing from the command line inside your project's folder: gradle wrapper --gradle-version=5.1.1 [*].

If gradle app:installDebug fails to execute correctly, then maybe you need to upgrade your Gradle buildscript. For updating from v.4.1RC1 to 5.1.1, the Gradle project provides a guide (1, 2) with breaking changes and deprecated features between minor releases, so that you can update gradually to the latest version.

Alternatively, if for some reason you can't or don't want to upgrade your Gradle buildscript, you can always choose to downgrade your Java version to one that Gradle 4.1RC1 supports running on.

[*] As correctly pointed out in the answer by @lupchiazoem, use gradle wrapper --gradle-version=5.1.1 (and not ./gradlew as I had originally posted there by mistake). The reason is Gradle runs on Java. You can update your gradle-wrapper using any working Gradle distribution, either your system-wide installed Gradle or the gradle-wrapper itself. However, in this case your wrapper is not compatible with your installed Java version, so you do have to use the system-wide Gradle (aka gradle and not ./gradlew).

Solution 2

As distributionUrl is still pointing to older version, upgrade wrapper using:

gradle wrapper --gradle-version 5.1.1

Note: Use gradle and not gradlew

Solution 3

Updating gradle/wrapper/gradle-wrapper.properties with the following version fixed it for me:

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

Solution 4

In my case the JAVA_HOME variable was set to /usr/lib/jvm/jdk-11.0.2/. It was sufficient to unset the variable like this:

$ export JAVA_HOME=

Solution 5

tl;dr: downgrade java by running update-alternatives

My system gradle version was 4.4.1, and the gradle wrapper version was 4.0. After running the command given by several other answers:

gradle wrapper --gradle-version 4.4.1

I still had the same error:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.4'.

It turns out java 11 wasn't supported until gradle 4.8, and my software repositories only had 4.4.1. (Also, upgrading to newer gradle version might have been incompatible with the package I was trying to compile.)

The answer was to downgrade java. My system actually had java8 already installed, and it was easy to switch between java versions by running this command and following the instructions:

sudo update-alternatives --config java

I ran the following comment:
```
./gradlew app:installDebug
```
only to be met with the log:
```

* Try:

My version of gradle is 5.1.1:

I'm not sure how to proceed (I tried upgrading/downgrading, but nothing has worked so far).

  according to this bug report , is it possible your gradle wrapper is older?
- tryman over 5 years
  
  You run the command ./gradlew which initiate the gradle version associated with this specific project. There is no guarantee that the project's version is the same as the one you have installed (5.1.1)

  Is that version info the result of gradle --version or ./gradlew --version? Gradle based projects often use a wrapper to make it easier for different developers to use the same Gradle version to build the project; this also makes builds more stable.

  that's the version of gradle --version
- tryman over 5 years
  
  Could you also go to your project folder and open the file: .../gradle/wrapper/gradle-wrapper.properties ? Open it with a simple text editor. The "distributionUrl" inside should tell us what the wrapper's version is.

  Updated my answer with the contents! Seems like the wrapper is on 4.1, so that's my issue?

@tryman thanks! for me it was the your update 2 that helped me. As a general rule of thumb I think I'd check the gradle version going forth.

This solved my problem too. jenv might have started my problems initially.
João Pimentel Ferreira about 5 years

you don't state exactly what is the CAUSE of the error. Different versions?
tryman about 5 years

What? I thought Update 2 was pretty clear. She was trying to run the Gradle wrapper of version 4.1RC1 with JDK11. Gradle added support for JDK11 at version 5.0. So what's your confusion @JoãoPimentelFerreira? That was the cause, the rest is the solution on how to update the project's wrapper to a later version that does support JDK11.

@tryman I have an apache project and understand nothing, zero, about gradle and I'm for two hours around this issue. Sorry, it is not clear what is the cause nor how to solve this issue.
João Pimentel Ferreira about 5 years

@tryman so the solution is to update the gradle wrapper version to be exactly the same as the system-wide version? That's my confusion

My (project's root folder)/gradle/wrapper/gradle-wrapper.properties has distributionUrl=https\://services.gradle.org/distributions/g‌radle-3.3-all.zip but my system-wide gradle version is 5.0. Can you kindly help please? Thank you
tryman about 5 years

Now it's my turn to be confused. If you indeed have both the gradle wrapper in your project folder and a system-wide Gradle installation in place, the above step by step solution should work for you. Did you try upgrading your wrapper by executing inside your project folder the update command gradle wrapper --gradle-version=5.0? Replace 5.0 with your desired version, I think now the latest is 5.4
tryman about 5 years

However a word of caution:Between version 3.3 of your wrapper an any version 5.x there are bound to be some breaking changes that you may or may not encounter. That's why in my answer I point you to first build your project with your systemwide Gradle to verify that everything runs smoothly with the version of 5.x you want to upgrade to before updating your project's wrapper. If in a hurry (I sense urgency in your tone) you can always use the system gradle directly or downgrade to an older JDK and catch up on upgrading your wrapper later.

for me GRADLE_HOME was updated(to 5.4.1``) but not gradle version(still pointing to older version 4.3) which is weird but restarting terminal worked fine. something weird with source ~/.bash_profile

Landed here from the same issue in Android Studio; I wonder why ./gradlew is not hitting Android Studio's bundled jdk 8? Clearly it does when I hit the 'play' button to build... This is a fairly serious problem for projects that can't/won't upgrade gradle version, given the Oracle Java 8 apocalypse.

Just a heads up DO NOT try this solution on Android Studio. I will break it.

Or just replace the version in gradle/wrapper/gradle-wrapper.properties distributionUrl=https\://services.gradle.org/distributions/g‌radle-5.1.1-all.zip Version 6 with JDK12 doesn't seem to work. 5.1.1 works fine, thank you.

I was using and older version of Gradle (4.1) on my system and trying to use Java 11. I guess that Java version was not supported by Gradle 4.1. So I just updated Gradle with brew upgrade gradle and it installed the latest (7.0) version of Gradle. Life is good again.

This was the only solution that worked fine for me on current Windows 10. Sdkman as proposed here should do the trick too, but is a bit tricky under Windows.
