Building Camel from Source
Camel uses Maven as its build and management tool. Download matlab mac free ucsd software download. If you don't fancy using Maven you can use your IDE directly or Download a distribution or JAR.
Linux/Mac OS X/Unix Downloads. Windows Downloads. Default assembly. Our default assembly is the best way to get started with Apache ServiceMix. Apache ServiceMix 4.5.2 (tar.gz) Apache ServiceMix 4.5.2 (zip) Source assembly. Use this if you want to build Apache ServiceMix from source yourself. Linux/Mac OS X/Unix Downloads. Apache ServiceMix 3. Endpoint operation information lost when routing through camel. SM-1136 - PreDestroy being called for each.
Prequisites
Required:
Apache Software Download
- Download and install Maven
(Maven 3.1.1 or newer is required to build Camel 2.14 onwards)
(Maven 3.2.5 or newer is required to build Camel 2.18 onwards)
(Maven 3.3.3 or newer is required to build Camel 2.20 onwards) - Get the latest Source
- Java
(1.7 or 1.8 to build Camel 2.14 onwards)
(1.8 to build Camel 2.18 onwards)
(1.9 experimental support for building Camel 2.19 onwards)
Maven options
To build camel maven has to be configured to use more memory:
Unix/Linux/Mac
Windows
To conserve memory with Java 8 you can set two additional Java options -XX:+UseG1GC to enable G1 garbage collector (default in Java 9) and -XX:+UseStringDeduplication to help decrease Maven memory usage (up to 1.5GB is required currently, but set it a higher):
Unix/Linux/Mac
Windows
You can try to experiment with parallel builds by adding -T1.5C to MAVEN_OPTS, but be wary as some of the plugins are not thread safe, and the console output will be intertwined. With parallel builds and when using the install goal you might experience race conditions with the local repository, using Takari Concurrent Local Repository will help with that.
A normal build
A normal build without running tests
A normal build without running tests but checkstyle verification enabled
Doing a Quick Build
Available as of Camel 2.6
The following skips building the manual, the distro and does not execute the unit tests. Paintbrush per mac download.
Updating the license headers
Proper license headers are enforced using Apache RAT and Checkstyle Maven plugins. To make it less tedious and error prone you can update the license headers by using:
Download Apache Mac
This can be invoked from any module, which makes it useful when working on components. You can find the various license headers that the Camel project uses in buildtools/src/main/resources/header-*.txt files. These are regenerated at build time from header.txt in the same directory.
Building source jars
If you want to build jar files with the source code, that for instance Eclipse can important so you can debug the Camel code as well. Then you can run this command from the camel root folder:
Working with karaf features
If you change anything in the features.xml from
platform/karaf
you can run a validation step to ensure the generated features.xml file is correct. You can do this running the following maven goal from the platform
directory.Executing unit tests using Ekstazi
Normally, when you execute the unit tests during your development cycle for a particular component, you are executing all the tests each time. This may become inefficient, when you are changing one class and the effect of this change is limited within the component having many unit tests. Ekstazi is a regression testing tool that can keep track of the test results and the changed classes so that unaffected tests can be skipped during the subsequent testing. For more details of Ekstazi, please refer to the Ekstazi page at http://www.ekstazi.org.
To use Ekstazi, you can run the tests with the maven profile ekstazi.
