César Soto Valero created STORM-3550:
----------------------------------------
Summary: Remove unused dependencies
Key: STORM-3550
URL: https://issues.apache.org/jira/browse/STORM-3550
Project: Apache Storm
Issue Type: Improvement
Components: storm-core
Reporter: César Soto Valero
There are some dependencies declared in *storm-core* that are not used. These
dependencies should be removed to make the core library slimmer and its
dependency tree less complex, which helps to maintain the project.
Unused dependencies with scope compile
* *joda-time:joda-time*
* *org.eclipse.jetty:jetty-util*
* *org.eclipse.jetty:jetty-servlet*
* *org.eclipse.jetty:jetty-servlets*
* *com.fasterxml.jackson.core:jackson-core*
* *com.fasterxml.jackson.dataformat:jackson-dataformat-smile*
* *commons-fileupload:commons-fileupload*
* *commons-codec:commons-codec*
Unused dependencies with scope test
* *org.hamcrest:java-hamcrest***
PS: For some of these dependencies, such as *jackson-core* and *commons:codec,*
I noticed that the same version is declared and included transitively in the
dependency tree. This is redundant and should be avoided. The following is an
excerpt of the Maven dependency tree that illustrates this situation.
{code:java}
+- com.fasterxml.jackson.core:jackson-core:jar:2.9.8:compile
+- com.fasterxml.jackson.dataformat:jackson-dataformat-smile:jar:2.9.8:compile
| \- (com.fasterxml.jackson.core:jackson-core:jar:2.9.8:compile - omitted for
duplicate)
{code}
{code:java}
+- commons-codec:commons-codec:jar:1.11:compile
+- org.apache.hadoop:hadoop-auth:jar:2.8.5:compile
| +- (commons-codec:commons-codec:jar:1.11:compile - omitted for duplicate)
. . .
