Oleksandr Shevchenko created HADOOP-15908:
---------------------------------------------

             Summary: hadoop-build-tools jar is downloaded from remote repository instead of using from local
                 Key: HADOOP-15908
                 URL: https://issues.apache.org/jira/browse/HADOOP-15908
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Oleksandr Shevchenko


HADOOP-12893 added "maven-remote-resources-plugin" to hadoop-project/pom.xml to verify LICENSE.txt and NOTICE.txt files which includes "hadoop-build-tools" remote resource bundles. 
{code}
<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-remote-resources-plugin</artifactId>
 <version>${maven-remote-resources-plugin.version}</version>
 <configuration>
 <resourceBundles>
 <resourceBundle>org.apache.hadoop:hadoop-build-tools:${hadoop.version}</resourceBundle>
 </resourceBundles>
 </configuration>
 <dependencies>
 <dependency>
 <groupId>org.apache.hadoop</groupId>
 <artifactId>hadoop-build-tools</artifactId>
 <version>${hadoop.version}</version>
 </dependency>
 </dependencies>
 <executions>
 <execution>
 <goals>
 <goal>process</goal>
 </goals>
 </execution>
 </executions>
 </plugin>
{code}

If we build only some module we always download " hadoop-build-tools" from maven repository.

For example run:
cd hadoop-common-project/
mvn test
Then we will get the following output:
{noformat}

If "hadoop-build-tools" jar doesn't exist in maven repository (for example we try to build new version locally before repository will be created ) we can't build some module:
For example run:
cd hadoop-common-project/
mvn test
Then we will get the following output:
{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-remote-resources-plugin:1.5:process (default) on project hadoop-annotations: Execution default of goal org.apache.maven.plugins:maven-remote-resources-plugin:1.5:process failed: Plugin org.apache.maven.plugins:maven-remote-resources-plugin:1.5 or one of its dependencies could not be resolved: Failure to find org.apache.hadoop:hadoop-build-tools:jar:3.2.0 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
{noformat}

Therefore, we need to limit execution of the Remote Resources Plugin only in the root directory in which the build was run.
To accomplish this, we can use the "runOnlyAtExecutionRoot parameter"
From maven documentation http://maven.apache.org/plugins/maven-remote-resources-plugin/usage.html
