Gradle 任务替换 .java 文件中的字符串不起作用

Question

我在 VersionConstants.java 文件下面..

public class VersionConstants {

    /**
     * This class does not need to be instantiated.
     */
    private VersionConstants() { }


    public static final String VERSION = "@VERSION@";

    public static final String PATCH_LEVEL = "@PATCH_LEVEL@";

    public static final String REVISION = "@REVISION@";

    public static final String BUILDTIME = "@BUILDTIME@";

    public static final String BUILDHOST = "@BUILDHOST@";
}

我按照这里的答案尝试了

task generateSources(type: Copy) {
    from 'src/replaceme/VersionConstants.java'
    into "$buildDir/generated-src"
    filter(org.apache.tools.ant.filters.ReplaceTokens, tokens: [
        "@VERSION@" : '1.0.0', 
        "@PATCH_LEVEL@" : '0.5',
        ...
    ])
}

但是，它正在处理 VersionConstants.java 文件，而不是用所需的值替换关键字，即 1.0.0 或 0.5 等

为什么？

Answer 1

知道了，我刚刚将 @VERSION@ 替换为 VERSION，效果非常好！

task generateSources(type: Copy) {
    from 'src/replaceme/VersionConstants.java'
    into "$buildDir/generated-src"
    filter(org.apache.tools.ant.filters.ReplaceTokens, tokens: [
        "VERSION" : '1.0.0', 
        "PATCH_LEVEL" : '0.5',
        ...
    ])
}

Answer 2

默认情况下，ReplaceTokens 具有 beginToken='@' 和 endToken='@'。所以改为

filter(ReplaceTokens, tokens: [
        "VERSION" : '1.0.0', 
        "PATCH_LEVEL" : '0.5',
        ...
    ])
