Failed to build mlsql-mllib with mlsql_plugin_tool

[chncaesar]

mlsql_plugin_tool build --module_name mlsql-mllib --spark spark311 failed with error:

[ERROR] /var/lib/jenkins/workspace/build_byzer_extension_jar/mlsql-mllib/src/test/java/tech/mlsql/plugins/mllib/ets/fe/SQLDataSummaryTest.scala:8: error: object test is not a member of package tech.mlsql
[INFO] import tech.mlsql.test.BasicMLSQLConfig

However, mlsql-extension-test-3.0_2.12-0.1.0-SNAPSHOT.jar is installed in local maven repo.
mlsql-extension-test jar is imported during test phase.

<dependency>
    <groupId>tech.mlsql</groupId>
    <artifactId>byzer-extension-tests-3.0_2.12</artifactId>
    <version>${project.version}</version>
    <scope>test</scope>
</dependency>

and maven command mvn -DskipTests clean package -Pshade -Pspark-3.0 -Pscala-2.12 -pl mlsql-mllib compiles testing code

We could remove <scope>test</scope> to fix this issue.
