+# central-deploy-bundles
+
+This is a multimodule example showing deployment to maven central 
+using the new central publishing rest api.
+
+The project consist of 
+- an aggregator
+- a common sub module
+- two sub modules that each depends on the common submodule
+
+Each module (including the main aggregator) will be deployed separately.
+I.e. when deploying the whole project, 4 zip files will be created and uploaded to central:
+1. The aggregator pom (+ asc, md5 and sha1 files)
+2. common, contains the pom, jar, javadoc and sources (all signed and with md5 and sha1 files)
+3. subA, contains the pom, jar, javadoc and sources (all signed and with md5 and sha1 files)  
+4. subB, contains the pom, jar, javadoc and sources (all signed and with md5 and sha1 files)
+
+## Running only this test
+```shell
+mvn -Prun-its verify -Dinvoker.test=central-deploy-bundles

+## Running the test manually
+```shell
+# copy resources
+mvn -Prun-its verify -Dinvoker.test=central-deploy-bundles
+cd target/it/central-deploy-bundles
