I'm getting the following error:
java.lang.NoSuchMethodError: org.elasticsearch.client.IndicesAdminClient.
prepareExists([Ljava/lang/String;)Lorg/elasticsearch/action/admin/indices/
exists/IndicesExistsRequestBuilder;
The code producing this was originally writtenfor ESearch 19.6 and am no
recompiling it for 90.5 version.
At this link: [grepcode.com](http://grepcode.com) search for that method in version 90.5[http://grepcode.com/file/repo1.maven.org/maven2/org.elasticsearch/elasticsearch/0.90.5/org/elasticsearch/client/IndicesAdminClient.java#IndicesAdminClient.prepareExists(java.lang.String[])](http://grepcode.com/file/repo1.maven.org/maven2/org.elasticsearch/elasticsearch/0.90.5/org/elasticsearch/client/IndicesAdminClient.java#IndicesAdminClient.prepareExists%28java.lang.String%5B%5D%29),
it doesn't show that method.
How do I replace this code? (I am just getting up to speed on this project:
It's my project, but I hired out the various parts, and we're getting ready
to launch and upgrading all the software first).

That method doesn't seem to have changed. I still see it:
[https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/client/IndicesAdminClient.java#L147](https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/client/IndicesAdminClient.java#L147)
Can you post a code fragment in case something is being overlooked?
BTW, are you using an IDE? Code completion really helps when transitioning
between libraries/APIs.
Cheers,
Ivan

The text scrap is below. The 'isExists()' code section was originally
'exists()', but that _IS_ a valid change. It wouldn't compile even until
that was changed. Now, at the point this is called, USUALLY, there is an
index already created. The code is NOT creating an index, however. I don't
THINK that the error I listed in the JUNIT test should say method does't
exist if it fails! I'm still trying to figure out why the index is not
being created.
(by the way, this is part of an 'osem[http://www.compass-project.org/docs/latest/reference/html/core-osem.html](http://www.compass-project.org/docs/latest/reference/html/core-osem.html)'
project) It was working fine on Java 1.6, ESearch 19.6.
```
private void ensureIndex(Class clazz) {
if (indexNames.containsKey(clazz))
return;
client.getClient().admin().cluster().prepareHealth()
.setWaitForYellowStatus().execute().actionGet();
String name = getIndexName(clazz);
if
```
(!client.getClient().admin().indices().prepareExists(name).execute()
.actionGet().isExists()) {
client.getClient().admin().indices().prepareCreate(name).execute()
.actionGet();
}
```
Map src = toObjectType(name,
toObjectType("properties", getMapping(clazz), null), null);
client.getClient().admin().indices().preparePutMapping(name)
.setType(name).setIndices(name).setSource(src).execute()
.actionGet();
indexNames.put(clazz, name);
}

Well, my partner is on the other end of the repo postings, and now the
main listed here is gone. But we now get a new kind of error that seems
harder to track down.

Turns out that ES has changed the method names of several methods in recent
code to bring them all more in line with a naming convention. 'exists'
became 'isExists' and 'sourcesAsMap' became 'getSourceAsMap'
Fixed these and some other niggly issues, and voila! It all works.
