Fix Maven Compilation Errors

Quick Diagnosis

Run mvn clean compile 2>&1 | tail -80 to identify error types:

Unreported exception - Method calls throw checked Exception but doesn't declare throws
Cannot find symbol - Missing import statements

Common Fixes

1. Missing throws Exception

Error pattern:

error: unreported exception Exception; must be caught or declared to be thrown

Cause: DTRow.getCell(String colName) throws Exception, calling methods must declare throws Exception.

Fix: Add throws Exception to method signature:

// Before
private static JSONObject createEndpointDescription(...) {

// After  
private static JSONObject createEndpointDescription(...) throws Exception {

2. Missing Imports

Common missing classes and their packages:

Class	Package
`UserConfig`	`com.gdxsoft.easyweb.script.userConfig.UserConfig`
`UserXItems`	`com.gdxsoft.easyweb.script.userConfig.UserXItems`
`UserXItem`	`com.gdxsoft.easyweb.script.userConfig.UserXItem`
`UserXItemValue`	`com.gdxsoft.easyweb.script.userConfig.UserXItemValue`
`UserXItemValues`	`com.gdxsoft.easyweb.script.userConfig.UserXItemValues`
`JSONArray`	`org.json.JSONArray`
`JSONObject`	`org.json.JSONObject`
`DTTable`	`com.gdxsoft.easyweb.data.DTTable`
`DTRow`	`com.gdxsoft.easyweb.data.DTRow`

Fix: Add import after existing imports:

import com.gdxsoft.easyweb.script.userConfig.UserConfig;
import com.gdxsoft.easyweb.script.userConfig.UserXItem;
import com.gdxsoft.easyweb.script.userConfig.UserXItems;
import org.json.JSONArray;

3. Test Compilation: EwaConfig vs IConfig

Error pattern (pre-existing, in bussinessXmlCreator tests):

不兼容的类型: com.gdxsoft.easyweb.script.template.EwaConfig无法转换为com.gdxsoft.easyweb.script.userConfig.IConfig

Cause: Test files use EwaConfig (template package) but BusinessXmlCreator.create() expects IConfig (userConfig package). These are different class hierarchies.

IConfig implementations: FileConfig, JdbcConfig, ResourceConfig (all in script.userConfig package).

Quick fix — skip test compilation:

mvn clean package -Dmaven.test.skip=true

Important: -DskipTests only skips test execution, test compilation still runs. Use -Dmaven.test.skip=true to skip both.

Workflow

Run mvn clean compile
Identify error type from output
Apply targeted fix (add throws or imports)
Verify with mvn clean compile
For packaging: mvn clean package -Dmaven.test.skip=true (avoids pre-existing test issues)
