java – 在Jenkins中使用Eclipse编译器来获取编译器警告/错误

批处理编译器方便地打包在一个单独的jar中,可以在Eclipse项目download page的“JDT Core Batch Compiler”部分下载,也可以在公共maven存储库中作为Eclipse ECJ.

如果您将ecj jar升级到ecj.dir,则可能会使用以下生成脚本来生成Eclipse警告,

build.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<project name="some-project" default="eclipse-warnings" basedir=".">
    <target name="eclipse-warnings" depends="init">        
        <property name="ecj.log.dir" value="${build.dir}/ecj" />
        <property name="ecj.warnings.file" value="${ecj.log.dir}eclipse_compiler_out.txt"/>
        <delete dir="${ecj.log.dir}" />
        <mkdir  dir="${ecj.log.dir}" />

        <property name="ecj.properties" value="${basedir}etcecjeclipse_compiler.properties" />                

        <!-- Redirect output to tempfile if you don't want results also on console -->
        <tempfile property="ecj.output.tempfile" suffix=".log" deleteonexit="true" />

        <echo message="Generating Eclipse warnings to ${ecj.warnings.file}" />        
        <java 
            jar="${ecj.dir}/ecj.jar"
            fork="true"
            maxmemory="512m"
            output="${ecj.output.tempfile}">

            <arg value="-cp" />
            <arg value="${toString:compile.classpath}" />
            <arg value="-d" />
            <arg value="none" />
            <arg value="-enableJavadoc" />
            <arg value="-log" />
            <arg value="${ecj.warnings.file}" />            
            <arg value="-${javac.source.version}" />
            <arg value="-properties" />
            <arg value="${ecj.properties}" />
            <arg value="${src.dir}" />
            <arg value="${test.dir}" />            
        </java>

        <!-- Echo number of warnings found -->
        <loadfile srcfile="${ecj.warnings.file}" property="ecj.warnings.file.summary">
            <filterchain>
                <tailfilter lines="1" />
            </filterchain>
        </loadfile>
       <echo message="${ecj.warnings.file.summary}" />
    </target>    
</project>

eclipse_compiler.properties包含编译器警告/错误设置,可以从项目的.settings / org.eclipse.jdt.core.prefs文件复制或在CompilerOptions类中定义.
