I'm using maven-antrun-plugin to execute a thrift shell command. I can compile one file per <exec> with <arg value="...path/to/file.thrift" />, but I would like to compile all .thrift files in a directory. How can I do this?
I tried using <arg value="...path/to/*.thrift" />, but Maven rejected this syntax.
在 maven 项目中编译 thrift 文件有几个选项：
Maven Thrift 插件支持生成源/测试源，修改时重新编译等。基本上，它是在 Maven 项目中使用 thrift 最方便的方式。
src/main/thrift（或src/test/thrift用于测试节俭资源）。将插件添加到pluginspom.xml 的部分：
<plugin>
<groupId>org.apache.thrift.tools</groupId>
<artifactId>maven-thrift-plugin</artifactId>
<version>0.1.11</version>
<configuration>
<thriftExecutable>/usr/local/bin/thrift</thriftExecutable>
</configuration>
<executions>
<execution>
<id>thrift-sources</id>
<phase>generate-sources</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>thrift-test-sources</id>
<phase>generate-test-sources</phase>
<goals>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
就是这样：下次调用mvn compilejava 源时，将从 Thrift 生成。生成的源码会被放到target/generated-sources/thrift/目录下，这个目录会被添加到java编译器的编译路径中。
您可以在 Github 上找到详细说明、示例等：https ://github.com/dtrott/maven-thrift-plugin 。
如果由于某种原因需要使用 antrun 插件，最好使用apply命令而不是exec处理一组文件。
我将只写一个 ant target 的基本概念，因为修改时的条件重新编译可能超出了这个问题的范围：
<target name="compile-thrift">
<!-- Define fileset of thrift files -->
<fileset id="thrift.src.files" dir="${src.thrift.dir}">
<include name="**/*.thrift"/>
</fileset>
<!-- Invoke thrift binary for each of these files -->
<apply executable="${thrift.compiler}" resultproperty="thrift.compile.result"
failifexecutionfails="true" failonerror="true"
searchpath="true" dir="${src.thrift.dir}">
<arg value="-o"/>
<arg value="${thrift.dest.dir}"/>
<arg value="--gen"/>
<arg value="java"/>
<srcfile/>
<fileset refid="thrift.src.files"/>
</apply>
</target>
如果出于某种原因绝对有必要使用 Antrun 插件和exec任务，那么有办法做到这一点。我建议不要这样做，因为它丑陋且不可移植，但它可能会起作用。用于xargs为文件列表调用 Thrift 编译器：
<exec dir="${src.thrift.dir}" executable="bash">
<arg line="ls * | xargs ${thrift.compiler} -o ${thrift.dest.dir} --gen java"/>
</exec>
我正在使用 thrift 0.10.0 搁浅，发现为了使用 maven-thrift-plugin 我必须提供generator选项：
<plugin>
<groupId>org.apache.thrift.tools</groupId>
<artifactId>maven-thrift-plugin</artifactId>
<version>0.1.11</version>
<configuration>
<thriftSourceRoot>${basedir}/src/main/resources/thrift</thriftSourceRoot>
<generator>java</generator>
</configuration>
<executions>
<execution>
<id>thrift-sources</id>
<phase>generate-sources</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>thrift-test-sources</id>
<phase>generate-test-sources</phase>
<goals>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
否则它会抱怨“未知选项 java:hashcode”。事实上，似乎 java 生成器中不再有这样的选项了。thrift --help提供以下选项：
java (Java):
beans: Members will be private, and setter methods will return void.
private-members: Members will be private, but setter methods will return 'this' like usual.
nocamel: Do not use CamelCase field accessors with beans.
fullcamel: Convert underscored_accessor_or_service_names to camelCase.
android: Generated structures are Parcelable.
android_legacy: Do not use java.io.IOException(throwable) (available for Android 2.3 and above).
option_type: Wrap optional fields in an Option type.
java5: Generate Java 1.5 compliant code (includes android_legacy flag).
reuse-objects: Data objects will not be allocated, but existing instances will be used (read and write).
sorted_containers:
Use TreeSet/TreeMap instead of HashSet/HashMap as a implementation of set/map.
generated_annotations=[undated|suppress]:
undated: suppress the date at @Generated annotations
suppress: suppress @Generated annotations entirely
