Building Camel from Source
Common Requirements
-
About 10Gb of free disk space for the compiled code and local Maven cache.
-
At least 3.5Gb of RAM.
-
A relatively modern operating system (Linux, Windows, macOS, *BSDs).
-
Other operating systems capable of running Java should work too, although that is not tested by the project
-
Prerequisites for Camel 3.x
-
Java 11 (we test using OpenJDK, but any modern JDK should be fine).
-
Apache Maven version 3.8.0 or greater to build the code. You can either use your own Maven package or build using the Maven Wrapper (
mvnw
) provided with the project.
Prerequisites for Camel 4.x
-
Java 17 (we test using OpenJDK, but any modern JDK should be fine).
-
Maven Wrapper can be used and is bundled.
-
Apache Maven version 3.9.0 or greater to build the code. You can either use your own Maven package or build using the Maven Wrapper (
mvnw
) provided with the project.
Maven
Running the Maven Wrapper mvnw
script with -v
parameter from the root directory of the project will reveal the recommended Maven version:
./mvnw -v
Apache Maven 1.2.3
Maven home: /home/user/.m2/wrapper/dists/apache-maven-1.2.3-bin/deadbeef/apache-maven-1.2.3
Java version: 17.0.5, vendor: Eclipse Adoptium, runtime: /home/user/java/17.0.5-tem
Default locale: en_IE, platform encoding: UTF-8
OS name: "linux", version: "6.3.7-200.fc38.x86_64", arch: "amd64", family: "unix"
If you do not like installing Maven manually, you can keep using mvnw
instead of mvn
.
Camel committers and experienced Camel contributors are may also use Maven Daemon |
Maven options
To build Camel maven has to be configured to use more memory, which is done automatically via the .mvn/jvm.config
file.
A normal build
Beware this runs all the unit tests which takes many hours.
mvn clean install
Building Camel 4
The following command will do a fast build.
mvn clean install -Dquickly
On Camel 4, you can also use |
The commands above will build Camel in a quick way: skipping build optional artifacts and running tests. In most modern computers, this should complete in at most 30 minutes (usually much less, for newer hardware).
