将gwt超级资源排除在最终战争之外

Question

对于具有以下结构的GWT项目：

src
/java
...
/super
/java
/text
/DecimalFormat.java

是否可以只在project-sources.jar中包含DecimalFormat.java，而不在project.jar(包含已编译的.class文件)中？

我目前使用的POM是：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration combine.self="override">
<excludes>
<exclude>**/src/emulation/*</exclude>
</excludes>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<configuration>
<includes>
<include>**/src/emulation/**/*.java</include>
</includes>
</configuration>
</plugin>

但以上所有内容都不起作用，因为路径应该是相对于src/java的sources文件夹的。同时尝试使用".."似乎也不起作用。

有没有什么插件可以更具体地处理这个问题？我看过托马斯·布罗耶的一些相关作品https://tbroyer.github.io/gwt-maven-plugin/add-super-sources-mojo.html.但我无法使它适用于这种情况。

谢谢！

Answer 1

我也无法使它与maven-source-plugin一起工作(由于某种原因，includes和excludes过滤器被完全忽略)。然而，在多模块配置中，这似乎是可能的。

家长

pom.xml

这是一个有点冗长的问题，因为我在本地实现了它，直到我的代码风格，但你可以完全忽略它，因为它不是什么新鲜事，只是两个子模块的父模块。

仿真子模块

仿真/pom.xml

这是Javajava.text包仿真类的pom。如上所述，我无法使maven-source-plugin与过滤器一起正常工作，但由于该模块是分离的，因此可以很容易地将源提供给目标源JAR文件(该文件自动具有sources分类器)。

仿真/src/main/java/text/text.gwt.xml

只是一个GWT模块定义，没有什么新鲜事。它可能也位于资源库中，但这更多的是一个代码定义，因此可以在这里进行测试。

<?xml version="1.0" encoding="UTF-8"?>
<module>
<inherits name="com.google.gwt.user.User"/>
<source path=""/>
</module>

仿真/src/main/java/text/DecimalFormat.java

仅用于测试目的的模拟类：

package java.text;
public final class DecimalFormat {
private final String pattern;
public DecimalFormat(final String pattern) {
this.pattern = pattern;
}
public String format(final double value) {
return "{pattern=" + pattern + ", value=" + value + "}";
}
}

应用程序子模块

这个pom.xml不包含GWT构建周期，它隐式地允许您自己进行构建。注意模拟模块依赖项的<classifier>sources</classifier>元素——这对GWT来说是最重要的，因为它只能编译Java源代码，而不能处理Java字节码。<scope>provided</scope>确保不将依赖项附加到目标工件(这是不必要的，因为所有JavaScript文件都是生成的，并且在服务器上预编译时不需要Java源代码)。

web容器的模块描述符。

app/src/main/webapp/index.html

用于加载应用程序引导程序的示例GWT应用程序容器页面。它将显示"格式化"的e和π。

<!DOCTYPE html>

<script type="text/javascript" language="javascript" src="test.ApplicationEntryPoint/test.ApplicationEntryPoint.nocache.js"></script>

<inherits name="java.text.Text"/>
<entry-point class="test.ApplicationEntryPoint"/>
<source path=""/>
</module>

app/src/main/java/test/ApplicationEntryPoint.java

示例应用程序：

package test;
import java.text.DecimalFormat;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.dom.client.Document;
import static java.lang.Math.E;
import static java.lang.Math.PI;
public final class ApplicationEntryPoint
implements EntryPoint {
private ApplicationEntryPoint() {
}
@Override
public void onModuleLoad() {
final Document document = Document.get();
final DecimalFormat decimalFormat = new DecimalFormat("###,###.###");
document.getElementById("e").setInnerText(decimalFormat.format(E));
document.getElementById("pi").setInnerText(decimalFormat.format(PI));
}
}

输出

e  | {pattern=###,###.###, value=2.718281828459045}
pi | {pattern=###,###.###, value=3.141592653589793}

mvn

GWT构建周期的Maven命令

• mvn clean gwt:run——启动嵌入式web容器
• mvn clean gwt:compile install-执行GWT编译(本质上是JavaScript文件生成)，打包一个war文件并将工件安装到本地存储库；工件可以很容易地部署到Tomcat

由于目标war中的WEB-INF/classes/test/ApplicationEntryPoint.class条目，可能还有更多需要微调的内容，但没有提供依赖关系的源代码。
