# Maven Google Appengine
|

|
|
||
|
|
|
||
|
|
#### maven-cli-plugin gebruiken als semi-hot-deployer
|
||
|
|
|
||
|
|
Zie [Mavenizing my project](http://blog.cloudme.org/2010/04/mavenizing-my-project/)
|
||
|
|
|
||
|
|
In plaats van betalende JRebel kan je bvb. voor GAE de jetty server op zetten met `gae:run`, maar alles in webapp ziet hij niet als een change.
|
||
|
|
|
||
|
|
* In Tab1: `mvn gae:run`.
|
||
|
|
* In Tab2: `mvn cli:execute` en dan commando's `compile war` in aparte tab die de eerste tab (nog actieve maven) oppikt dan.
|
||
|
|
|
||
|
|
Andere mogelijkheid is natuurlijk voor niet-GAE dingen, `jetty:run` gebruiken (zie [code/build/maven]({{< relref "wiki/code/build/maven.md" >}})).
|
||
|
|
|
||
|
|
:exclamation: de plugin is **niet werkend met maven 3**, zie https://github.com/mrdon/maven-cli-plugin/wiki/Maven-3.0-Support -

Hiermee kan je:
|
||
|
|
|
||
|
|
1. `mvn gae:unpack` uitvoeren om de GAE SDK in uw maven repo te unpacken zodat `${gae.home}` niet nodig is in de pom (vanaf 0.9.5)
|
||
|
|
1. `mvn gae:run` uitvoeren om een devserver te starten

##### Andere versie
|
||
|
|
|
||
|
|
Een oudere versie (??) is deze:
|
||
|
|
|
||
|
|
```xml
|
||
|
|
<plugin>
|
||
|
|
<groupId>com.google.appengine</groupId>
|
||
|
|
<artifactId>appengine-maven-plugin</artifactId>
|
||
|
|
<version>${appengine.target.version}</version>
|
||
|
|
</plugin>
|
||
|
|
```
|
||
|
|
|
||
|
|
Hiermee kan je:
|
||
|
|
|
||
|
|
1. `mvn appengine:devserver` gebruiken om lokaal een jetty op te starten, en
|
||
|
|
1. `mvn appengine:update` om te deployen via de commandline.
