我有一个用Java，App Engine，Gradle和Cloud Endpoints编写的后端。我使用App Engine Gradle Plugin中的functionalTests测试端点。这一切都很好。
我遇到的问题是其中一个端点将任务发布到不存在的模块。至少在本地开发服务器上是真的。在生产中，模块确实存在。如何告诉本地开发服务器该模块是否存在？
public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap args) throws WorkflowException {
Session participantSession = null;
Session replicationSession = null;
// ResourceResolver resourceResolver = null;
try {
log.info("Inside ActivatemyAppPageProcess ");
Session session = workflowSession.getSession();
if (replicateAsParticipant(args)) {
String approverId = resolveParticipantId(workItem, workflowSession);
if (approverId != null) {
participantSession = getParticipantSession(approverId, workflowSession);
}
}
if (participantSession != null)
replicationSession = participantSession;
else {
replicationSession = session;
}
WorkflowData data = workItem.getWorkflowData();
String path = null;
String type = data.getPayloadType();
if ((type.equals("JCR_PATH")) && (data.getPayload() != null)) {
String payloadData = (String) data.getPayload();
if (session.itemExists(payloadData))
path = payloadData;
}
else if ((data.getPayload() != null) && (type.equals("JCR_UUID"))) {
Node node = session.getNodeByUUID((String) data.getPayload());
path = node.getPath();
}
ReplicationOptions opts = null;
String rev = (String) data.getMetaDataMap().get("resourceVersion", String.class);
if (rev != null) {
opts = new ReplicationOptions();
opts.setRevision(rev);
}
opts = prepareOptions(opts);
if (path != null) {
ResourceCollection rcCollection =
ResourceCollectionUtil
.getResourceCollection(
(Node) this.admin.getItem(path),
(ResourceCollectionManager) this.rcManager);
boolean isWFPackage = isWorkflowPackage(path, resolverFactory, workflowSession);
List<String> paths = getPaths(path, rcCollection);
for (String aPath : paths)
if (canReplicate(replicationSession, aPath)) {
if (opts != null) {
if (isWFPackage) {
setRevisionForPage(aPath, opts, data);
}
this.replicator
.replicate(replicationSession,
getReplicationType(),
aPath,
opts);
} else {
this.replicator
.replicate(replicationSession,
getReplicationType(),
aPath);
}
} else {
log.debug(session.getUserID() + " is not allowed to replicate " + "this page/asset " + aPath + ". Issuing request for 'replication");
Dictionary properties = new Hashtable();
properties.put("path", aPath);
properties.put("replicationType", getReplicationType());
properties.put("userId", session.getUserID());
Event event = new Event("com/day/cq/wcm/workflow/req/for/activation", properties);
this.eventAdmin.sendEvent(event);
}
} else {
log.warn("Cannot activate page or asset because path is null for this workitem: " + workItem.toString());
}
} catch (RepositoryException e) {
throw new WorkflowException(e);
} catch (ReplicationException e) {
throw new WorkflowException(e);
} finally {
if ((participantSession != null) && (participantSession.isLive())) {
participantSession.logout();
participantSession = null;
}
}
}
我在获得例外的地方运行的代码：

答案 0 :(得分：0)
我自己想通了。显然，有一种方法可以与本地开发服务器同时运行所有模块。然后它可以找出模块。
如果其他人想要这样做，请创建ear模块并将Gradle App Engine插件应用于该模块。
