多线程ant signjar偶尔会报错
Multi-threading ant signjar occasionally causes errors
我的 Gradle 通过 ant.signjar 任务构建了将近 200 个 jar。为了加快速度，我决定尝试使用来自 here and here 的信息对其进行多线程处理。仅供参考：这在我的 Core Duo 笔记本电脑上从 25 分钟减少到 7 分钟（快 4 倍！）。
但是，有时运行成功，有时运行失败，我不知道为什么。这可能与多线程有关，但我无法解释为什么它不会每次都发生。
我的代码现在看起来像这样。
import groovy.io.FileType
import static groovyx.gpars.GParsPool.withPool
//This is so that we can use the Groovy parallel library in the build script
buildscript {
repositories {
mavenLocal()
mavenCentral()
//Change to this if you have your own repo
maven {
url "http://localhost:8081/nexus/content/groups/public/"
}
}
dependencies {
classpath group: 'org.codehaus.gpars', name: 'gpars', version: '1.2.1'
}
}
task signWebstartJars() << {
File unsignedFolder = new File('build/maven')
File signedFolder = new File('signed-libs')
signedFolder.mkdirs()
def list = []
unsignedFolder.eachFileRecurse(FileType.FILES) { file ->
list << file
}
list.sort()
//Create a closure that allows us to run the actual ant task multi-threaded later
def antClosure = {
println "Updating manifest: " + it
//Manifest needs extra attributes added for security
ant.jar(destfile: it, update: true) {
delegate.manifest {
attribute(name: 'permissions', value: 'all-permissions')
attribute(name: 'codebase', value: '*')
}
}
println "Signing the jar: " + it
ant.signjar(
destDir: signedFolder,
alias: alias,
sigfile: sigfile,
jar: it,
keystore: keystore,
storepass: storepass,
storetype: storetype,
preservelastmodified: "true",
verbose: "true"
)
}
//Use twice as many CPUs for no. of threads
result = withPool(Runtime.runtime.availableProcessors() * 2) {
list.collectParallel antClosure
}
}
有时会出现的错误是这样的。
* What went wrong:
Execution failed for task ':signWebstartJars'.
> : manifest doesn't support the nested "jar" element.
* Try:
Run with --debug option to get more log output.
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':signWebstartJars'.

它seems like AntBuilder 不是线程安全的。在闭包中创建一个新的 AntBuilder 修复它。我从 Gradle 论坛粘贴了下面的片段，因为它比我在原始 post.

它seems like AntBuilder 不是线程安全的。在闭包中创建一个新的 AntBuilder 修复它。我从 Gradle 论坛粘贴了下面的片段，因为它比我在原始 post.
中的示例短import groovyx.gpars.GParsPool
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath group: 'org.codehaus.gpars', name: 'gpars', version: '1.1.0'
}
}
task signMyJars {
doLast {
List filesToSign = [
file('file1.jar'),file('file2.jar'),file('file3.jar')
]
GParsPool.withPool {
filesToSign.eachParallel { f ->
def antLocal = project.createAntBuilder()
antLocal.signjar(
alias: "my key alias",
jar: f,
keystore: "my_key_store",
storepass: "key_store_pass",
storetype: "pkcs12",
)
}
}
}
