If you followed the installation instructions, and aren’t able to execute your Gradle build, here are some tips that may help. Show
If you installed Gradle outside of just invoking the Gradle Wrapper, you can check your Gradle installation by running gradle --version in a terminal. You should see something like this: ❯ gradle --version ------------------------------------------------------------ Gradle 6.5 ------------------------------------------------------------ Build time: 2020-06-02 20:46:21 UTC Revision: a27f41e4ae5e8a41ab9b19f8dd6d86d7b384dad4 Kotlin: 1.3.72 Groovy: 2.5.11 Ant: Apache Ant(TM) version 1.10.7 compiled on September 1 2019 JVM: 14 (AdoptOpenJDK 14+36) OS: Mac OS X 10.15.2 x86_64 If not, here are some things you might see instead. Command not found: gradleIf you get "command not found: gradle", you need to ensure that Gradle is properly added to your PATH. JAVA_HOME is set to an invalid directoryIf you get something like: ERROR: JAVA_HOME is set to an invalid directory Please set the JAVA_HOME variable in your environment to match the location of your Java installation. Permission deniedIf you get "permission denied", that means that Gradle likely exists in the correct place, but it is not executable. You can fix this using chmod +x path/to/executable on *nix-based systems. Other installation failuresIf gradle --version works, but all of your builds fail with the same error, it is possible there is a problem with one of your Gradle build configuration scripts. You can verify the problem is with Gradle scripts by running gradle help which executes configuration scripts, but no Gradle tasks. If the error persists, build configuration is problematic. If not, then the problem exists within the execution of one or more of the requested tasks (Gradle executes configuration scripts first, and then executes build steps). IssueI am currently trying to create a .gitlab-ci.yml file in which an Android Studio project is automatically build. The file structure in my GIT repo looks like this: the_app .gitlab-ci.yml README.mdMy .gitlab-ci.yml looks like this: image: jangrewe/gitlab-ci-android variables: ANDROID_COMPILE_SDK: "30" before_script: - export GRADLE_USER_HOME=$(pwd)/.gradle - apt-get update -y && apt-get install wget -y build: script: - cd ./ISSD_application - chmod +x ./gradlew - ./gradlew assembleDebug artifacts: paths: - app/build/outputs/But now I get the error that says: ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH. Please set the JAVA_HOME variable in your environment to match the location of your Java installation.The Java installation that is used for the Android project is on my computer and not in the GIT-repo. How can I set the JAVA_HOME variable correctly so the project can build? SolutionIndeed JAVA_HOME is not set in the image but java binary is located under /usr/bin/java. You can set JAVA_HOME in the same way you set GRADLE_USER_HOME, in before_script section : before_script: - export GRADLE_USER_HOME=$(pwd)/.gradle - export JAVA_HOME="/usr/bin/java" - apt-get update -y && apt-get install wget -y Answered By - Nicolas Pepinster Hi i tried to exxecute a gradle command in bitbucket pipeline definitions:services: java: image: openjdk:8 pipelines: default: - step: name: Build And Test services: - java script: - bash ./gradlew clean build - bash ./gradlew test - step: name: configure gcloud deployment: test image: google/cloud-sdk:214.0.0-alpine services: - java - docker caches: - gradle script: - gcloud auth configure-docker --quiet - docker login -u _json_key -p "$GCR_JSON_KEY" https://gcr.io - bash ./gradlew bake -Penv=test -PisRelease=false --info --stacktrace when it tried to execute the latest task - bash ./gradlew bake -Penv=test -PisRelease=false --info --stacktraceit give the error JAVA_HOME is not set and no 'java' command could be found in your PATH.what is the issue in this case? How to fix JAVA_HOME errorsThere’s nothing worse than installing your favorite Java-based application — such as Minecraft, Maven, Jenkins or Apache Pig — only to run into a JAVA_HOME is set to an invalid directory or a JAVA_HOME is not defined correctly error as soon as you boot up the program. Well, there’s no need to fret. Here’s how to fix the most common JAVA_HOME errors. How to fix JAVA_HOME not found errors It’s worth noting that there aren’t standardized JAVA_HOME error messages that people will encounter. There are many different ways that a given JAVA_HOME error might be logged. For example, one of the most common JAVA_HOME configuration problems arises from the fact that the environment variable has never actually been set up. Such a scenario tends to trigger the following error messages:
How do you fix the JAVA_HOME not found problem? Well, you fix this by in the Windows environment variable editor where you can actually add a new system variable. If you know your way around the Windows operating system, you should be able to add the JAVA_HOME environment variable to your configuration and have it point to the installation root of your JDK within minutes. The Windows 10 setting looks like this: Fix JAVA_HOME not found errors As mentioned above, the JAVA_HOME variable must point to the installation root of a JDK, which means a JDK must actually be installed. If one isn’t, then you better hop to it and get that done. The JAVA_HOME is set to an invalid directory fix The next most common JAVA_HOME error message is JAVA_HOME is set to an invalid directory. The error message is delightfully helpful, because it tells you in no uncertain terms the environment variable does in fact exist. And, it also tells you it’s not pointing to the right place, which is helpful as well. All you need to do to fix this error is edit the JAVA_HOME variable and point it to the correct directory. The JAVA_HOME environment variable must point to the root of the installation folder of a JDK. It cannot point to a sub-directory of the JDK, and it cannot point to a parent directory that contains the JDK. It must point directly at the JDK installation directory itself. If you encounter the JAVA_HOME invalid directory error, make sure the name of the installation folder and the value of the variable match. An easy way to see the actual value associated with the JAVA_HOME variable is to simply echo its value on the command line. In Windows, write: >/echo %JAVA_HOME% C:/_JDK13.0On an Ubuntu, Mac or Linux machine, the command uses a dollar sign instead of percentages: :-$ echo $JAVA_HOME /usr/lib/jvm/java-13-oracleHow to find JAVA_HOME in Mac or Ubuntu Linux computers. Steer clear of the JDK \bin directory One very common developer mistake that leads to the JAVA_HOME is set to an invalid directory error is pointing JAVA_HOME to the \bin sub-directory of the JDK installation. That’s the directory you use to configure the Windows PATH, but it is wrong, wrong, wrong when you set JAVA_HOME. If you point JAVA_HOME at the bin directory, you’ll need to fix that. This misconfiguration also manifests itself with the following error messages:
Other things that might trigger this error include spelling mistakes or case sensitivity errors. If the JAVA_HOME variable is set as java_home, JAVAHOME or Java_Home, a Unix, Linux or Ubuntu script will have a hard time finding it. The same thing goes for the value attached to the JAVA_HOME variable. The JAVA_HOME does not point to the JDK error One of the most frustrating JAVA_HOME errors is JAVA_HOME does not point to the JDK. Here’s a little bit of background on this one. When you download a JDK distribution, some vendors include a Java Runtime Environment (JRE) as well. And when the JAVA_HOME environment variable gets set, some people point it at the JRE installation folder and not the JDK installation folder. When this happens, we see errors such as:
To fix this issue, see if you have both a JRE and JDK installed locally. If you do, ensure that the JAVA_HOME variable is not pointing at the JRE. JAVA_HOME and PATH confusion After you’ve downloaded and installed the JDK, sometimes another problem can plague developers. If you already have programs that installed their own version of the JDK, those programs could have added a reference to that specific JDK in the Linux or Windows PATH setting. Some programs will run Java using the program’s availability through the PATH first, and JAVA_HOME second. If another program has installed a JRE and put that JRE’s \bin directory on the PATH, your JAVA_HOME efforts may all be for naught. However, you can address this issue. First, check the Ubuntu or Windows PATH variable and look to see if any other JRE or JDK directory has been added to it. You might be surprised to find out that IBM or Oracle has at some prior time performed an install without your knowledge. If that’s the case, remove the reference to it from the PATH, add your own JDK’s \bin directory in there, and restart any open command windows. Hopefully that will solve the issue. Of course, there is never any end to the configurations or settings that can trigger JAVA_HOME errors.

How do you fix error JAVA_HOME is not set and no Java command could be found in your path?Solution 1. Just open your terminal.. Run this command flutter config –android-studio-dir='<path to android studio>. flutter doctor.. Thats It.. How do you fix please set the JAVA_HOME variable in your environment to match the location of your Java installation?To set JAVA_HOME, do the following: Right click My Computer and select Properties. On the Advanced tab, select Environment Variables, and then edit JAVA_HOME to point to where the JDK software is located, for example, C:\Program Files\Java\jdk1.
Why JAVA_HOME is not working?Verify JAVA_HOME
Enter the command echo %JAVA_HOME% . This should output the path to your Java installation folder. If it doesn't, your JAVA_HOME variable was not set correctly. Please make sure you're using the correct Java installation folder, or repeat the steps above.
What happens if JAVA_HOME is not set?If any program that requires a Java runtime fails to find the JAVA_HOME environment variable upon startup, or if the JAVA_HOME environment variable is misconfigured, it will result in some of the following error messages to be displayed: A Java installation exists but JAVA_HOME has been set incorrectly.
