Git

Since Camel 2.16

Both producer and consumer are supported

The Git component allows you to work with a generic Git repository.

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-git</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI Format

git://localRepositoryPath[?options]

URI Options

The producer allows to do operations on a specific repository.
The consumer allows consuming commits, tags and branches on a specific repository.

The Git component supports 3 options, which are listed below.

Name Description Default Type

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

basicPropertyBinding (advanced)

Deprecated Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

The Git endpoint is configured using URI syntax:

git:localPath

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

localPath

Required Local repository path

String

Query Parameters (15 parameters):

Name Description Default Type

branchName (common)

The branch name to work on

String

password (common)

String

remoteName (common)

The remote repository name to use in particular operation like pull

String

remotePath (common)

The remote repository path

String

tagName (common)

The tag name to work on

String

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

type (consumer)

The consumer type. There are 3 enums and the value can be one of: commit, tag, branch

GitType

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. There are 3 enums and the value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

allowEmpty (producer)

The flag to manage empty git commits

true

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

operation (producer)

The operation to do on the repository. There are 18 enums and the value can be one of: clone, init, add, remove, commit, commitAll, createBranch, deleteBranch, createTag, deleteTag, status, log, push, pull, showBranches, cherryPick, remoteAdd, remoteList

String

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

Producer Example

Below is an example route of a producer that add a file test.java to a local repository, commit it with a specific message on master branch and then push it to remote repository.

from("direct:start")
        .setHeader(GitConstants.GIT_FILE_NAME, constant("test.java"))
        .to("git:///tmp/testRepo?operation=add")
        .setHeader(GitConstants.GIT_COMMIT_MESSAGE, constant("first commit"))
        .to("git:///tmp/testRepo?operation=commit")
        .to("git:///tmp/testRepo?operation=push&remotePath=https://foo.com/test/test.git&username=xxx&password=xxx")
        .to("git:///tmp/testRepo?operation=createTag&tagName=myTag")
        .to("git:///tmp/testRepo?operation=pushTag&tagName=myTag&remoteName=origin")

Consumer Example

Below is an example route of a consumer that consumes commit:

from("git:///tmp/testRepo?type=commit")
                        .to(....)

Spring Boot Auto-Configuration

When using git with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-git-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 4 options, which are listed below.

Name Description Default Type

camel.component.git.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.git.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.git.enabled

Whether to enable auto configuration of the git component. This is enabled by default.

Boolean

camel.component.git.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
