You can set the maven properties such as local maven repository location, remote maven repositories and their authentication credentials including
the proxy server properties via commandline properties when starting the Dataflow server or using the SPRING_APPLICATION_JSON
environment property
for the Dataflow server.
The remote maven repositories need to be configured explicitly if the apps are resolved using maven repository except for local
Data Flow server. The other
Data Flow server implementations (that use maven resources for app artifacts resolution) have no default value for remote repositories.
The local
server has repo.spring.io/libs-snapshot
as the default remote repository.
To pass the properties as commandline options:
$ java -jar <dataflow-server>.jar --maven.localRepository=mylocal
--maven.remote-repositories.repo1.url=https://repo1
--maven.remote-repositories.repo1.auth.username=repo1user
--maven.remote-repositories.repo1.auth.password=repo1pass
--maven.remote-repositories.repo2.url=https://repo2 --maven.proxy.host=proxyhost
--maven.proxy.port=9018 --maven.proxy.auth.username=proxyuser
--maven.proxy.auth.password=proxypass
or, using the SPRING_APPLICATION_JSON
environment property:
export SPRING_APPLICATION_JSON='{ "maven": { "local-repository": "local","remote-repositories": { "repo1": { "url": "https://repo1", "auth": { "username": "repo1user", "password": "repo1pass" } }, "repo2": { "url": "https://repo2" } }, "proxy": { "host": "proxyhost", "port": 9018, "auth": { "username": "proxyuser", "password": "proxypass" } } } }'
Formatted JSON:
SPRING_APPLICATION_JSON='{ "maven": { "local-repository": "local", "remote-repositories": { "repo1": { "url": "https://repo1", "auth": { "username": "repo1user", "password": "repo1pass" } }, "repo2": { "url": "https://repo2" } }, "proxy": { "host": "proxyhost", "port": 9018, "auth": { "username": "proxyuser", "password": "proxypass" } } } }'

Depending on Spring Cloud Data Flow server implementation, you may have to pass the
environment properties using the platform specific environment-setting capabilities. For instance,
in Cloud Foundry, you’d be passing them as |
