## Problem description
使用“eclipse-codetemplate.xml”后，eclipse 新建 java 类文件样式不对，需要单独 format 一遍


正确应该是：
```
package com.ngailab;

public class Test {

}
```

## Advice

建议改为如下，去掉行首的空格
```
${filecomment}
${package_declaration}

${typecomment}
${type_declaration}
```

Open eclipse-codetemplate.xml and inspect lines 19-23, especially the leading spaces around ${package_declaration}, ${typecomment}, and ${type_declaration}. Remove the unintended indentation and verify that a newly created Eclipse Java class has the expected package and class layout without requiring manual formatting.
