java - Protocol Buffer 编译器maven插件

Question

我在我的 POM 中配置了 Protocol Buffer 编译器插件，每当构建项目时都会执行该插件。这个编译器插件在 Windows 中运行良好，但现在我将我的项目移到了 ubuntu PC 上，需要为此使用合适的替代方案。

        <plugin>
            <artifactId>maven-antrun-plugin</artifactId>
            <executions>
                <execution>
                    <id>compile-protoc</id>
                    <phase>generate-sources</phase>
                    <configuration>
                        <tasks>
                            <mkdir dir="src/main/resources/protocolBuffers/compiled" />
                            <path id="proto.path">
                                <fileset dir="src/main/proto">
                                    <include name="**/*.proto" />
                                </fileset>
                            </path>
                            <pathconvert pathsep=" " property="proto.files" refid="proto.path" />
                            <exec executable="src/main/resources/protocolBuffers/compiler/protoc" failonerror="true">
                                <arg value="--java_out=src/main/resources/" />
                                <arg value="-I${project.basedir}/" />
                                <arg line="${proto.files}"/>
                            </exec>
                        </tasks>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

我在 Ubuntu netbeans 中尝试构建项目时看到以下输出

--- maven-antrun-plugin:1.3:run (compile-protoc) @ Px10App ---
Executing tasks

如何使编译器插件在 Ubuntu netbeans 中工作？

Answer 1

这个带有内置的 protoc(它最初基于 igor-petruk/protobuf-maven-plugin，但它带有为 Linux、Mac/OSX 和 Windows 捆绑的 protoc 二进制文件)。在运行时它检测平台并执行相应的二进制文件

https://github.com/os72/protoc-jar-maven-plugin

这是一个例子:

<plugin>
    <groupId>com.github.os72</groupId>
    <artifactId>protoc-jar-maven-plugin</artifactId>
    <version>3.11.1</version>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <protocVersion>2.4.1</protocVersion>
                <inputDirectories>
                    <include>src/main/protobuf</include>
                </inputDirectories>
            </configuration>
        </execution>
    </executions>
</plugin>
