## Building Apache Hop
### From source repository
Required:
- [OpenJDK](https://openjdk.java.net/) Java 17 compiler. Make sure to update your JDK to the latest possible patch
version.
Recommended:
- [Maven](http://maven.apache.org/) 3.6.3 or higher
Verify Maven Java version: (should be Java 17 to compile properly without skipping tests)
mvn -version
Clone Hop to a local repository:
$ git clone https://github.com/apache/hop.git
Change into the clone repository and build: \
We provide two ways to build the code, if you have the correct Maven version installed you can use following commands:
$ cd hop
$ mvn clean install
We have also added mavenwrapper which simplifies build by using the correct Apache Maven version when it is not
available on the system
$ cd hop
$ ./mvnw clean install
### From release archive
You can download a source release [here](https://downloads.apache.org/hop/)
Required:
- [OpenJDK](https://openjdk.java.net/) Java 17 compiler or higher. Make sure to get the latest updates to support recent
features like dark mode on the various platforms.
- [Maven](http://maven.apache.org/) 3.6.3 or higher
Verify Maven Java version: (should be Java 17 to compile properly without skipping tests)
mvn -version
Unzip the archive
$ tar -xf apache-hop*.tar.gz
Change into the clone repository and build: \
We provide two ways to build the code, if you have the correct Maven version installed you can use following commands:
$ cd apache-hop-*
$ mvn clean install
We have also added mavenwrapper which simplifies build by using the correct Apache Maven version when it is not
available on the system
$ cd apache-hop-*
$ ./mvnw clean install
## Run Apache Hop
