* GH-3554: Eval remote dir on each synchToLocal Fixes https://github.com/spring-projects/spring-integration/issues/3554 The `remoteDirectoryExpression` was introduced into an `AbstractInboundFileSynchronizer` to let end-user to evaluate a remote directory on each poll (essentially on each `synchronizeToLocalDirectory()` call). The fix for the https://jira.spring.io/browse/INT-4491 introduced a regression when such an expression was evaluated only once when we call a `setRemoteDirectory()`. So, an original purpose of this option was lost and we don't get an actual remote dir on each poll * Remove `evaluateRemoteDirectory()` method and its usage since it doesn't reflect expectation of the remote dir expression property * Reinstate the `remoteDirectoryExpression` evaluation in the `synchronizeToLocalDirectory()` * Propagate the result of that expression into further methods for copying files * Remove setting of the `remoteDirectory` variable into a global `EvaluationContext` of the `AbstractInboundFileSynchronizer` instance since it is not thread-safe * Instead create an `EvaluationContext` locally for each `synchronizeToLocalDirectory()` call and set the `remoteDirectory` variable into this scoped instances * Generate a local file name from the `localFilenameGeneratorExpression` against locally created `EvaluationContext` with the mentioned `remoteDirectory` variable * Cover the expected functionality with a unit-test **Cherry-pick to `5.4.x` & `5.3.x`** * * Fix `testRemoteDirectoryRefreshedOnEachSynchronization` according PR review

Checking out and Building
To check out the project and build from the source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
If you encounter out of memory errors during the build, increase an available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
